The heat capacity of substance A is twice that of substance B. If samples of equal masses of each absorb the same amount of heat, which substance undergoes the greater change in temperature? The specific heat capacity of silver is 0.24J/gC. How many joules of heat are required to heat 0.50g of silver from 25C to 78C ? Question 4 2 pts Calculate the change in temperature resulting from adding 31.3kJ of heat to a 450g block of aluminum. The specific heat of aluminum is 0.90J/gC. Question 5 2 pts If 372J of heat is added to 5.00g of water initially at 23.0C, what is the final temperature of the water? (Specific heat of water is 4.184J/gC )
