Hello!
In this case, given the mass, temperature change and specific heat, it is possible to compute the required heat in joules as shown below:
Now, since 1 cal =4.184 J, this result in calories is:

Answer:
If a gas contracts by 1/273 of its volume for each degree of cooling, it should contract to zero volume at a temperature of –273°C; this is the lowest possible temperature in the universe, known as absolute zero.It appeared that an “ideal gas” at constant pressure would reach zero volume at what is now called the absolute zero of temperature. Any real gas actually condenses to a liquid or a solid at some temperature higher than absolute zero. Therefore, the ideal gas law is only an approximation to real gas behaviour.
Cells are considered one of the characteristics of life because all living things are made of cells
