Describe a method to determine the specific heat capacity of a solid, like a piece of copper ?
In an experiment to determine the specific heat capacity of a solid following operations were
made:
Mass of calorimeter + stirrer = x kg
Mass of water = y kg
Initial temperature of water t1℃
Mass of solid = z kg
Temperature of solid = t2 ℃
Temperature of mixture = t ℃
Specific heat capacity of calorimeter and water are c1 and c2 respectively. Express the specific
heat capacity c of the solid in terms of the above data.
What is meant by global warming?
Write two advantages of high specific heat capacity of water.
Explain, why do sandy soils, get heated up quickly as compared to wet soils?
1 kg of water freezes to form ice at 0°C. What amount of heat is withdrawn?
A substance is in the form of a solid at 0°C. The amount of heat added to this substance and the temperature of the substance are plotted on the following graph:
If the specific heat capacity of the solid substance is 500 J/kg °G, find from the graph, the mass of the substance.
Calculate the ratio of two specific heats of polyatomic gas molecules.
Read this activity and answer the following questions.
