How is the transference of heat energy by radiation prevented in a calorimeter?
200 g mass of certain metal of 83°C is immersed in 300 g of water at 30°C the final temperature
is 33°C. Calculate the specific heat capacity of the metal Assume that the specific heat capacity
of water is `4.2 J g^-1K^-1`
1.0 kg of water is contained in a 1.25 kW kettle. Calculate the time taken for the temperature of water to rise from 25° C to its boiling point of 100°C. Specific heat capacity of water = 4.2 J g-1K-1.
Explain the terms melting ?
Give scientific reasons for the following:
It is much easier to skate on rough ice than on glass.
Fill in the following blank using suitable word:
The amount of heat required to change the state of a physical substance without any change of temperature is called .......... of the substance.
Which requires more heat: 1 g ice at 0°C or 1 g water at 0°C to raise its temperature to 10°C? Explain your answer.
Name the material of which it is made of. Give two reasons for using the material stated by you.
A copper calorimeter of mass 50g contains 100g of water at 20°C. A metallic piece of mass 250 g is heated to 100°C and is then dropped into the calorimeter. The contents of the calorimeter are well stirred and its final highest temperature is recorded to be 28 °C. If the specific heat capacity of water is 4.2 J/g°C and of copper is 0.4 J/g°C, find:
(i) the heat gained by water,
(ii) the heat gained by calorimeter,
(iii) total heat supplied by the metal piece, and
(iv) the specific heat capacity of metal.
