What is Carnot cycle Class 11?

Cycle of processes in a Carnot engine Engine absorbs heat Q1 at temperature T1. An adiabatic process takes place inside the engine because of which there is increase in the temperature of the engine from T1 to T2 but no flow of heat. As system is releasing heat so it is isothermal contraction. Click to…

How long does it take a portable AC unit to cool a room?

In short, if you have interconnecting rooms that are connected by a door and have no space in between, your portable AC could cool both of the rooms. Your unit should be powerful enough for equivalent area of rooms in this scenario. However, this is not so effective and efficient way of cooling. Click to…

Does ice absorb heat from air?

During freezing, the temperature of a substance remains constant while the particles in the liquid form a crystalline solid. Because particles in a liquid have more energy than particles in a solid, energy is released during freezing. This energy is released into the surroundings.

Does pressure increase or decrease in a compressor?

Because the volume has decreased, the particles will collide more frequently with the walls of the container. Each time they collide with the walls they exert a force on them. More collisions mean more force, so the pressure will increase. When the volume decreases, the pressure increases. Click to see full answer What causes compressor…

Why does ice absorb more heat than water?

When ice is placed in a glass of water whose molecules are moving at a greater rate, the ice begins to absorb energy, because heat always travels from regions of relative warmth to colder areas in order to equalize temperatures. In other words, ice absorbs heat from the water. Click to see full answer Why…
