What is the principle of Calorimetry?
How will you determine the specific heat capacity of a liquid like olive oil by the method of mixtures?
200 g of hot water at 80°C is added to 400 g of cold water at 10°C. Neglecting the heat taken by the container, calculate the final temperature of the mixture of water. Specific heat capacity of water = 4200 J kg-1K-1.
Give scientific reasons for the following:
Sand mixed with salt is often spread over the icy roads in winter.
A refrigerator converts 100 g of water at 20°C to ice at -10°C in 73.5 minutes. Calculate the average rate of heat extraction from water in watt. (Sp. heat of ice= 2100 J/kgK, sp. heat of water = 4200 J/kgK, Sp. latent heat of ice = 336000 J/kg.)
Which contains more heat: 1 G water at 100°C or 1 g steam at 100°C? Give reason.
1 kg of ice at 0o is heated at constant rate and its temperature is recorded after every 30 s till steam is formed at 100o C. Draw a temperature time graph to represent the change of phase.
The process of converting a substance from solid state to gaseous state is called condensation.
Name the material used for making a Calorimeter.
