how are a Joule, a calorie, and a watt alike?

while i cant give you scientific terms, the best short answer i can give is that they are all forms of energy.

The SI (International System of Units) unit to express energy, work, or quantity of heat is the Joule (J). 1 J = 1 Newton x 1 Meter.
848039
Depends on the system of units.\n\nIn SI all forms of energy are measured in Joules.\n\nThe Joule is a derived unit not a fundamental one - 1 Joule = 1 kilgramme metre^2/second^2.

multiply the mass of the water by the specific heat and the (temperature required minus the ambient temperature).that will give you the energy in joules.if you know in how much time you want this temperature to be achieved you can calculate the power as power is nothing but the rate at which the energy is dispensed

1 calorie is 4.18 Joules\n1000 is 1 kilo\nThe ratio is always 4.18:1\nso... 1 kilocalorie=4.18 kilojoules

Watts = Volts * Amps\n\nSo if you have amps, multiply it by the voltage (if it's a standard electrical device for the home, the voltage is 120 Volts) to get watts.\n\n1000 Watts = 1 kilowatt

Watt is a unit of power....ampere is a unit of current.\n\nPOWER = Current X Voltage

power is the amount of work done in unit time \nit is measured in Joules per second , dude

Volts times amps = watts.

The units of:\n[Power] = Watts\n[Current] = Amps\n[Time] = Seconds\n[Energy] = Joules\n     \n      also\n\n[Energy] = kWh\n\n1kWh = 3.6 X10^6 Joules\n\nPower = Current X Voltage\n\nEnergy = Power X Time \n\nAfter performing the previous calculation, the units of energy must be converted from Joules to kWh, since electric companies charge in dollar per kWh.\n\n\n$ = Energy (measured in kWh) * Cost of energy in Dollars per kWh\n\nUsually, the cost of electric energy is in the neighborhood of $0.05 and $0.10 per kWh.

A calorie is the ammount of energy needed to raise the temp. of one ml of water one degree C.  A Calorie is 1000 times that, or the energy needed to raise one L. of water one degree C.

The SI unit: calorie (cal)

kg m^2\n------- = Joule\ns^2\n\nb = kg m/s

kWh is NOT Kilowatts per hour. It is Kilowatt Hours and is the measure of the amount of energy drawn in one hour hour if it is drawn at a rate of one Kilowatt.\n\nKilowatts are a measure of Energy per unit time ie. Joules/s so kWh are J/s x 3600 s ie. measured in Joules.\n\nThe peak is just the highest energy usage rate in a given time period

I am assuming the energy in this context as "heat energy". Then the answer is NO. It depends on the temperature.\n\nHeat flows from body of high temperature to body of low temperature.\n\nImagine a small tank (10ltr) on second floor and a big tank with 100 lt on first floor. If we connect these, water flows from top tank to below tank.\nHeight is synonymous to Temperature.\nAmount of water is synonymous to Heat energy.\n\nPS: Another similarity is electricity.\nTemperature = height of water = voltage\nheat flow = water flow = current\nheat energy = amount of water = charge\nheat resistance = pipe resistance = electrical resistance

Quantity of heat (Q), measurement = joule (J)\nSpecific heat capacity in liquid, measurement = c/(kJ kg^-1)

Calories is the unit to measure heat, where as Fat in terms of Chemistry is long chain molecules of fatty acids due to which Fat is solid at lower temperatures. \nIn common language calories is used to tell the amount of heat we can get from a specific food, and fat is the extra calories which are stored in body.
