The pressure of air in a car tyre is 2 atmospheres and the temperature of air inside is `27^@C`. If the tyre hursts suddenly, what would be the resulting temperature ? (gamma= 1.4).

A fog drop has a diameter of 2xx10^-6 m. Calculate the pressure inside the drop in atmospheres , if the temperature is 20^@ C. Assume the air pressure outside the drop one atmosphere and surface tension of water=0.0727N/m (1atm=1.013xx10^5N/m^2) .

The density of air near the earth's surface is 1.3kg m^-3 and the atmosphere pressure is 1.0xx10^5Nm^-2 . If the atmosphere has uniform density, same as that observed at the surface of the earth , what would be the height of the atmosphere to exert the same pressure .

A volume of dry air at 27^@C is compressed (b) suddenly to one third of its volume.Find the resulting temperature in each., case, taking y = 1.4 for air.

Calculate the final temperature when a given mass of a gas at 0^@C is suddenly compressed adiabatically to a pressure 20 times the initial pressure gamma=1.42

100 c.c of air are measured at 20^@C .If the temperature be raised to 50^@C , what will be the volume, pressure remaining constant.

Define co-efficient of linear and cubical expansion and establish a relation between them . The length of a copper wire is measured 40 cm by a metal scale when both are at the temperature of 25^@C . What would be the length of wire measured by the same scale when both are at 55^@C ? (alpha "for metal" = 1.1 xx 10^(-7) @C^(-1) and alpha for copper = 1.7 xx 10^(-7)@c^(-1))

Ten litres of dry air at 27^@C and 76 cm pressure is compressed adiabatically to a volume of 03 liter. Assuming gamma = 1.4 for dry air, fine the resulting pressure and temperature.
