Specific heat is the heat necessary to raise the temperature of 1kg of a given material by 1∘C. This specific heat value varies by material with metals having relatively low specific heat with organic materials and water being very high. The specific heat of mercury is 140 J/kg∘C and the specific heat of water is 4190 J/kg∘C.
1.140 J of heat energy are transferred to 30.9 g of mercury. By how much does the temperature increase in Celsius?
2. How much heat is needed to raise the temperature of 30.9 g of water by the same amount? Please answer in J.
