To stop a volcano from destroying a local town you come up with a plan to drop a huge ice cube into the lava to cool it down so that it becomes solid rock. There is 40,000 kg of lava which has the following properties: Temperature = 1300° C %3D Melting point of lava = 1200° C %3D Specific heat of the lava = 840 J/Kg*C Latent heat of fusion for lava = 418 KJ/Kg How much ice at 0° C is needed to cool all the lava down into its solid form? Latent heat of fusion for water = 333 KJ/Kg Specific heat of water = 4186 J/Kg*C [Your answer will be in terms of Kg]

![8000 J of heat are added to an ideal monatomic gas in
an isovolumetric process. The gas then undergoes an
isobaric expansion at 0.2 atm pressure. The two
processes happen such that the final temperature is
equal to the initial temperature.
What is the change in volume for the gas?
