When 400 J of heat are slowly added to 10 mol of an ideal monatomic gas, its temperature rises by . What is the work done on the gas?
Professional divers sometimes use heliox, which is a mixture by mole of helium and oxygen. A perfectly rigid scuba tank with a volume of 15 L contains heliox at an absolute pressure of Pa and at a temperature of .
Determine how many moles of helium are in the tank. Use a value of 4.003 g/mol for the molar mass of helium.
How many moles of oxygen are in the tank?
The diver descends to a point where the sea temperature is while using a negligible amount of the heliox mixture. How much heating of the water around the scuba tank results from the change in temperature of the tank?
2.50 mol of air and 2.50 mol of argon are each heated at constant volume, raising their temperatures from to .
How much energy is transferred to the air? Model the air as being diatomic.
How much energy is transferred to the argon?
