Calculate the amount of heat required to completely sublime 28.0 g of solid dry ice (co2 at its sublimation temperature. the heat of sublimation for carbon dioxide is 32.3 kj/mol.

Answer : The amount of heat required to complete sublime of is 20.5 kJ.

Explanation :

First we have to calculate the moles of .

Now we have to calculate the amount of heat required to complete sublime of .

As, 1 mole of on sublimation required heat = 32.3 kJ

So, 0.636 mole of on sublimation required heat = 0.636 × 32.3 kJ = 20.5 kJ

Therefore, the amount of heat required to complete sublime of is 20.5 kJ.

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire
