Answer:B. A liquid changes to a solid.

Explanation:

A Liquid changes to solid when pressure

increases from 1 atm to 10 atm at -40°C

What is the concept for this?

  • The increase in pressure on liquid it forms a solid
  • If the pressure above the liquid is decreased sufficently, the liquid form a gas

How to solve this problem?

  • Here the Freezing point is -78.33°C i.e [-109°F]
  • above this temperature CO2 remains in liquid state

So, given at -40°C

CO2 will be in liquid state and as per the concept explained above by increasing the pressure on liquid we get the solid state

Thus , With CO2 a liquid phase change to a solid

phase when pressure increases 1 atm to 10atm at -40°C
