1. A piece of copper block of mass 24g at 2300C is placed in a copper calorimeter of
mass 60g containing 54g of water at 31oC. Assuming heat losses are negligible,
calculate the final steady temperature of the mixture. [Specific hest capacity of water
= 4200Jkg – 1 K – 1
, specific heat capacity of copper = 400Jkg – 1 K – 1
].
2. The lower and upper fixed points marked on a mercury in glass thermometer are
210mm apart. The end of the mercury column in the tube is 49mm above the lower
fixed point in a room. What is the temperature of the room in degree celcius.?
