According to second law of thermodynamic, heat flows from higher to lower temperature region. Heat is the transfer of energy from an object at higher temperature to an object at a lower temperature. so energy flows from warmer to colder objects.

Rooms are heated using gas heaters by convection and radiation. Convection is the transfer of heat by molecules of a fluid from denser medium to a less dense medium. Similarly Radiation is a phenomenon of heat transfer in the form of particles or waves.

Heat can also be transferred by the movement of fluids—liquids and gases. Convection is heat transfer by the movement of currents within a fluid. During convection, heated particles of fluid begin to flow. This flow transfers heat from one part of the fluid to another.

Best direction for study Students should face East and North-East while studying and North for those aiming to go for higher studies. As East is the direction of rising sun and North of Kuber (lord of wealth and abundance) thus these directions are considered to be sacred in vastu.

Heat is the transfer of kinetic energy between molecules. If the velocity is more, the kinetic energy will be more so that the heat is more. Since temperature is the measure of heat, the temperature increases as the velocity increases.

Vertical rays travel over a shorter distance and thus lose less heat. They are mostly concentrated on a smaller area. On the other hand, slanting rays travel over a larger distance as a result of which they lose more heat.

The movement of heat by moving a hot fluid (air, water) away from the heat source into a colder area we call convection. ... In short, convection is the transfer of heat by moving mass. The current is the motion of this mass. Convection creates currents.

Conduction is the transfer of heat by direct contact; requires a solid. Convection is the transfer of heat in a fluid; can be a liquid or a gas. Both require matter. Radiation does not.

While conduction is the transfer of heat energy by direct contact, convection is the movement of heat by actual motion of matter; radiation is the transfer of energy with the help of electromagnetic waves.

North, east, south, and west are the four cardinal directions, often marked by the initials N, E, S, and W. East and west are at right angles to north and south. East is in the clockwise direction of rotation from north. West is directly opposite east.

To do so the warm air will move towards the colder air so that the energy is more uniformly distributed. This creates a force known as the temperature gradient force, which pushes the air from the warmer air towards the colder air, resulting in wind.

In thermodynamics, heat means energy which is moved between two things when one of them is hotter than the other. Adding heat to something increases its temperature, but heat is not the same as temperature. The temperature of an object is the measure of the average speed of the moving particles in it.

The layers of atmosphere are heated through. Solution : Radiation from sun and convection currents, are responsible for heating.

One natural example of convection currents is wind. As the Sun shines down on an area of land, it heats the air above the ground. That warm air rises. As it rises, cooler air moves in to take the place at the bottom.

Simply heat is the sum of kinetic energy of atoms or molecules. In thermodynamics, heat means energy which is moved between two things when one of them is hotter than the other. Adding heat to something increases its temperature, but heat is not the same as temperature.

Heat: the Transfer of Thermal Energy Heat can be given off in three different processes: conduction, convection, or radiation. Conduction occurs when thermal energy is transferred through the interaction of solid particles.

The difference between heat flow and heat flux is that heat flux it the heat flow per area unit, as described in the formula below. Heat is the flow of energy due to difference of temperature. The area is perpendicular to the heat flow direction, regardless of the heat trnsfer mechanism.
