A. Choose all the situations that are an indirect measurement.
1. Ethylene glycol, used as a coolant in automotive engines, has a specific heat capacity of 2.42 J/gC. Calculate q when 3.65kg of ethylene glycol is cooled from 32C to 85C.
2. A piece of copper metal initially at 100.C is dropped into a coffee cup calorimeter containing 50.0g H2O. If the water temp goes up by 5.0C, if the specific heat of water is 4.184 J/gC, how much heat was given off by the copper?
3. When Karl Kaveman adds 459g of chilled grog, at 4C, to his new granite mug, the grog increases in temperature to 13C. If the grog has a specific heat of 3.269 J/gC, how much heat did the mug release?
4. If 1.45J of heat are added to a 2.00g sample of copper metal and the temperature of the metal increases by 1.88C, what is the specific heat of copper?
