Give a mathematical relation between Heat Capacity and Specific Heat Capacity.
Discuss the role of high specific heat capacity of water with reference to climate in coastal areas.
Explain the term boiling ?
104g of water at 30°C is taken in a calorimeter made of copper of mass 42 g. When a certain mass of ice at 0°C is added to it, the final steady temperature of the mixture after the ice has melted, was found to be 10°C. Find the mass of ice added. [Specific heat capacity of water = 4.2 Jg–1°C–1 ; Specific latent heat of fusion of ice = 336 Jg–1; Specific heat capacity of copper = 0.4 Jg–1°C–1] .
Decide the unit for specific heat capacity.
Numerical Problem.
What is the heat in joules required to raise the temperature of 25 grams of water from 0°C to 100°C? What is the heat in Calories? (Specific heat of water = `(4.18"J")/("g"°"C")`
A diatomic gas undergoes adiabatic change. Its pressure 'P' and temperature 'T' are related as p ∝ Tx, where x is ______.
The molar specific heats of an ideal gas at constant pressure and volume are denoted by Cp and Cv, respectively. If `gamma = "C"_"p"/"C"_"v"` and R is the universal gas constant, then Cv is equal to ______.
