Answer:

at T = 0ºC the change of state is from the solid state to the gaseous state

Explanation:

In this exercise we are asked about the changes of state, from the data we will assume that the material is water.

Water can exist in three solid states, liquid and gas, in a graph of pressure ℗ against temperature (T) there is a point called triple at T = 0.01ºC, below this point the curve has two states at high pressure solid and low pressure gas.

As a result of the previous ones at T = 0ºC the change of state is from the solid state to the gaseous state

Which of the following materials is able to absorb large amounts of energy without changing temperature very much? air concrete
Alinara [238K]
At normal temperature, specific heat of air = 1.006 concrete =0.96 water =4.187 (all are in KJ/KgK) soil = 0.80 So, from <span>Q=mcDeltaT</span><span> higher the specific heat lower the change in temperature for same quantity of heat supplied. Therefore, water is the answer.</span>
