Take timer and thermometer.\n\nHeat the first metal, and check temperature every 5 seconds or so and write the temperature in a table.\n\nDo it with all the metals you want to check and compare the results.\n\nit should take about an hour depending on how many differnt metals you want to check, and it dont cost much.

Would you like to qualify that question with something?\nFor example, what material can absorb heat with the smallest increase in temperature.\n\nHeat is a form of energy.  Temperature is the measure of the average kinetic energy of the molecules of a substance.\nAll materials will absorb heat (energy) and their temperature will increase.  How much their temperature increases when a given material absorbs a given amount of heat depends on its specific heat.\nThe specific heat of a material lets up know how much a substance's temperature will increase after abosorbing a given amount of energy.\n\nThe change in temperature of substance experiences can be calculates using the following,\nQ = m*c*(delta T)\nWhere Q is the heat energy, m is the mass of the object, c is the specific heat, and (delta T) is the change in temperature.\n\nA low specific heat means the material will experience a larger increase in temperature (all other things being constant) than a material with a higher specific heat.\n\nThe specific heat of all materials vary.\nAs a general rule, metals tend to have low specific heats and gasses tend to have higher specific heats (there is a reason for this, but it is beyond this answer's scope), but this is not always the case.\n\nWater for example has a pretty high specific heat at about 4.186 J/g degree C (or to simplify, 1 calorie).  By comparison, lead metal has a specific heat of only  1.28 J/g C.\nThis means that the temperature of 1 gram of water will increase by 1 degree C when it absorbs 4.186 Joules of energy.  Likewise, when water cools 1 degree C, it releases 4.186 J of energy.

Not all solids conduct heat with the same efficiency, but it's true all solids conduct heat!

I'm not sure what your question is.  A thermoelectric thermometer should have a sensor made of two metals.  It's a thermocouple.  Obviously the heat capacity of any metal is very low.

Put a metal which has higher activity than Silver

Metals are shiny and are good conductors of heat and electric current. They are malleable and ductile.\nNon-metals are dull, and are poor conductors of heat and electric current. They're brittle and unmalleable.

malleable and ductile lustrous conduct heat and electricity high melting points almost all are solids at room temp except mercury

Platinum wires are chemical and heat resistant (higher melting point than copper, silver, gold, etc.).  They are NOT better conductors (the opposite), it is rather their ability to tolerate higher temperatures that makes them useful.\n\nAlso, platinum/platinum-alloy wire pairs are used for thermocouples that are accurate at high temperatures, and pure platinum wire is used for resistance thermometers that are used for the same purpose.

errr, grind metals to a fine powder and mix them together and press them and you can get alloys physically impossible to make by forging.\n\numm, grind metal very fine so the oxidise and use them to make metal fires, such as "thermalite" for welding traintracks.

In chemical qualitive analysis, this is known as a flame test.  Many metals (and some non-metals) have distinctive colors.\n\nThe heat of the flame excites one or more electrons of the metal atom causing it to go to a higher energy state.  When the electron returns to the "ground state" electromagnetic energy is released and this appears as light of a specific color.

gold because it holds and conducts heat quicker and longer.

This isn't the final answer, but it is a clue:\n\nhttp://www.thesheetmetalshop.com/pdf_manual/Problem1.pdf

E=mc∆T is the equation you want to use for this situation, where E is energy, m is mass, c is the specific heat, and ∆T is the change in temperature.  Now, the heat lost by the alloy is equal to the heat gained by the water, right?  So look what we can do:\nmc∆T=mc∆T\nwhere the left side of the equation is talking about the metal, and the right side of the equation is talking about the water.  Let's start pluggin in values.  We'll leave the left c value as a variable because that's what we're solving for.  \n36.0 g *c*(178 oC -30.6 oC)=185.0 g*(4.184 J/g*K)*(30.6 oC-25.0 oC)\nThe trickiest thing about that step is the temperatures: the metal started at 178 and goes down to 30.6; the water starts at 25 and goes up to 30.6.  \nNow evaluate that equation and solve for c. \nc=.817 J/g*K

You could try to make an accurate experimental thermometer by glueing two strips of dissimilar metals together along their lengths. Perhaps try copper and steel or copper and aluminum or steel and aluminum.  Try perhaps one half inch wide by six inch long strips.  Use sheets of metal that are equally thin.  Perhaps cut the strips from aluminum soda cans and steel soup cans, etc.  Use a magnet to check for steel vs aluminum.  Glue the strips together using epoxy or super glue.  Attach one end of the combined strip to a firm base and leave one end free to move in front of a paper scale.  You now have a bimetalic thermometer.  The thermometer can be made to be more sensitive by using greater length strips and bending the strips into a spiral and attaching a pointer to the free end of the spiral to amplify movement.  This is how most oven thermometers are built except the metals are joined without glue.  The principal of operation of a bimetalic thermometer is that one  metal expands or contracts more or less than another metal.  When joined, a temperature change causes the combined strip to bend.  You can calibrate your thermometer by marking its "pointer" position at two or more large temperature changes then calculating the total deflection divided by the total temperature difference to get deflection per degree (either F or C).  Be careful with tin snips and epoxy or super glue.  Good luck.\n\nAs an alternative, you can make a highly accurate experimental thermometer by winding very thin insulated copper wire (like that used in toy motors) around a wooden spool and connecting the scraped   wire ends to an accurate ohmmeter to measure resistance change vs temperature change.  Calibrate as before but remember that calibration temperatures must be steady long enough for any lag to catch up.  This is called a resitance thermometer and accuracy will depend on the length and thinness of wire and sensitivity of your ohmmeter.  Also the ohmmeter should not cause enough current to flow in the wire to heat the wire.  Observe for drift (increase in resistance and temperature) while taking measurements.

Of the metals commonly used for conductors, copper has the highest conductivity. Silver is more conductive, but due to cost it is not practical except as a thin plating to mitigate skin effect losses at high frequencies. Because of its ease of connection by soldering or clamping, copper is still the most common choice for most light-gauge wires.\n\nCompared to copper, aluminium has worse conductivity per unit volume, but better conductivity per unit weight. In many cases, weight is more important than volume making aluminium the 'best' conductor material for certain applications. For example, it is commonly used for large-scale power distribution conductors such as overhead power lines. In many such cases, aluminium is used over a steel core that provides much greater tensile strength than would the aluminium alone [1][2].\n\nGold is occasionally used for very fine wires such as those used to wire bond integrated circuits to their lead frames. The contacts in electrical connectors are also commonly gold plated or gold flashed (over nickel). Contrary to popular belief, this is not done because gold is a better conductor; it isn't. Instead, it is done because gold is very resistant to the surface corrosion that is commonly suffered by copper, silver, or tin/lead alloys. This corrosion would have a very detrimental effect on connection quality over time; gold-plating avoids that.
