2 how many joules of heat are needed to raise the temp. of a 25.0 g of water from 10.0 C to 60.0 C

3 if it takes 118 J of heat to increase the temp. of a 5.00 g block of silver by 15.0 C, what is the specific heat of silver

4 if you supplied 76.4 J of heat to a block of ice to make it melt what must the mass of the ice have been

5 Determine the amount of energy required to raise the temperature of a 10.0 g sample of aluminum from 25.0°C to 58.0°C

6 If it takes 118 J of heat to increase the temperature of a 32.8 gram block of silver by 15.0°C what is the specific heat capacity of silver

7 If you supplied 418 J of heat to a block of ice to make it melt what must the mass of the ice have been

8 A 25.0 g bolt made of an alloy absorbed 250 joules of heat as its temperature changed from 25.0°C to 78.0°C. What is the specific heat of the alloy
