300 J of heat energy are transferred to 40 g of mercury. 1. By how much does the temperature of mercury increase? The specific heat of mercury is 140 J/kg⋅K. Express your answer using two significant figures.
a. 100 J of heat energy are transferred to 20 g of mercury. By how much does the temperature increase? b. How much heat is needed to raise the temperature of 20 g of water by the same amount?
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...
