To determine The heat absorbed by the bubble as it rises. Explanation The heat absorbed by the bubble will be equal to the work done. The temperature is constant so that the process is isothermal. Write the equation for the work done in an isothermal process. − W = n R T ln ( V 2 V 1 ) (I) Here, W is the work, n is the number of moles, R is the universal gas constant, T is the temperature, V 2 is the final volume and V 1 is the initial volume. Write the ideal gas equation. p V = n R T (II) Here, p is the pressure, V is the volume, n is the number of moles, R is the universal gas constant and T is the temperature. n and R constant. For the isothermal process T is also constant so that right-hand side of the above equation is constant. This implies the left-hand side also must be constant. Write the equation for the isothermal process. p 1 V 1 = p 2 V 2 Here, p 1 is the initial pressure and p 2 is the final pressure. Rearrange the above equation. V 2 V 1 = p 1 p 2 (III) Put equations (II) and (III) in equation (I). − W = p V ln ( p 1 p 2 ) (IV) Write the equation for the volume of the bubble. V = 1 6 π d 3 Here, d is the diameter of the bubble

Energy transfer

The flow of energy from one region to another region is referred to as energy transfer. Since energy is quantitative; it must be transferred to a body or a material to work or to heat the system.

Molar Specific Heat

Heat capacity is the amount of heat energy absorbed or released by a chemical substance per the change in temperature of that substance. The change in heat is also called enthalpy. The SI unit of heat capacity is Joules per Kelvin, which is (J K-1)

Thermal Properties of Matter

Thermal energy is described as one of the form of heat energy which flows from one body of higher temperature to the other with the lower temperature when these two bodies are placed in contact to each other. Heat is described as the form of energy which…
