They use refrigerant, which freon is a type of. For the cooling mechanism of a refrigeration machine, a compressor pushes the liquid coolant out and into the expansion evaporator. The evaporator uses the cool temperature from the coolant and uses the forced air from a fan (example for AC or fridge) and into an expansion valve that regulates its flow to the next step. It then goes to a condenser where it goes back into a fluid from gas form and back to the compressor. I left a few steps out (it's been a while).

If an astronaut travels to different planets, which of the following planets will the astronaut’s weight be the same as on Earth
Nataly_w [17]
<h2>Astronaut travels to different planets - Option 4 </h2>

If an astronaut travels to different planets, none of the planets will the astronaut’s weight be the same as on Earth. On jupiter, weight will be more than the weight on earth. For instance if an astronaut has 100kg on earth then he will have 252 kg on jupiter.

On Mars, weight will be less than the weight on the earth. For instance, if an astronaut has 68 kg on earth then he will has 26 kg on mars. On Mercury, weight of an astronaut will be less than the weight on earth. Example if he has 68 kg on earth then he will have 25.7kg on mercury.

Hence, none of these planets the weight of astronaut will be same as on earth.

What is the relation between inertia and mass?
aleksandr82 [10.1K]

Answer:

The tendency of an object to resist changes in its state of motion varies with mass. Mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.
