The latent heat of steam also increases. It is because increasing the pressure compresses the expanding molecules of water hence more amount of heat energy is required to overcome the compression and make it boil, same happens in case of change of state, with the increase in pressure, more amount of energy is required for enough expansion of water molecules to change its state. So latent heat of steam also increases.

Heat transfer is the movement of thermal energy from one object or substance to another. The three types of heat transfer are conduction, convection, and radiation. Each type of heat transfer has its own specific characteristics and applications in our daily lives.

Conduction: Conduction is the transfer of heat from one substance to another through direct contact, such as when a hot pan is placed on a cold surface. The heat is transferred from the hotter object to the cooler one until they...

Even though air is a bad conductor of heat, it carries away heat from our body due to convection. Hence, we feel cold without clothes.

Emissivity is the ratio of a surface’s ability to emit radiant energy compared with the ability of a perfect black body of the same area at the same temperature.

Emissivity (ϵ) = e/E

Two thin blankets usually warmer than one thick blanket because air is trapped between them. And the air is bad conductor of heat. It doesn’t pass heat from our body to the surroundings.

Water kept insilver pot will cooler faster.

Explanation:

Becausesilver deflects light.In the process it deflects heat.We all know black absorbs light. Sosilver pot is cooler than black pot for the storage of water.People should use silver pots in summer season.

Hot water pipes are often painted black because black absorbs heat more effectively than other colors. When hot water flows through a pipe, the pipe loses heat to its surroundings. If the pipe is painted black, it will absorb more heat from the hot water, which can help to keep the water hot as it flows through the pipe.

In addition, black absorbs more light than other colors, which makes it a good choice for hot water pipes because it helps to reduce the amount of light reflection from the...

The emissivity of a material is a dimensionless quantity that represents its ability to emit thermal radiation compared to an ideal black body. It has no unit.

The blackening of the bottom surface of cooking utensils is due to the deposition of soot and carbon from incomplete combustion, while the upper surface remains cleaner due to less exposure to direct heat and combustion by-products.
