When 5 moles of an ideal gas having non- linear molecules is heated from 1000 K to 2000 K at cal. Assume that all the degree of freedom in molecules are active in this temperature range and the heat capacity of gas is temperature independent. The atomicity of gas is :[in2=0.7]

A lead ball at 25^@ C is dropped from a height of 2 km. It is heated due to air resistance and it is assumed that all of its kinetic energy is used in increasing the temperature of ball. Find the final temperature of the ball.

With what velocity must a lead bullet at 50^(@)C strike against an obstacle in order that the heat produced by the arrest of the motion, is sufficient of melt it, assuming that all the heat produced remains within the bullet? (Specific heat capacity of lead =31cal kg^(-1)K^(-1) , melting point of lead =335^(@)C , specific latent heat capacity of lead =5370 cal kg^(-1)K^(-1) and J=4.2 joules cal^(-1) )

A bullet moving with a velocity of 230 m/s is stopped by a block of wood. Calculate the rise in temperature of the bullet assuming that all the heat generated is retained by the bullet. Specific heat capacity of lead = 126 J/kg/K.

One mole of diatomic gas is being heated in a closed tank 300K up to 1000K During the process part of the molecules dissociate At 1000K the energy of the diatomic molecules are only half of that of the whole gas By what factor has the gas pressure increased (P_(final)//P_(initial)) ? (The oscillation of the molecules are not to be taken in account)

Calculate the time required to beat 20kg of water from 10^(@)C to 35^(@)C using an immersion heater 1000W Assums that 8% of the power input is used to bead the water specific beat capacity of water = 4200J kg^(-1)K^(-1)

Carbon monoxide is carried around a closed cyclic processes abc , in which bc is an isothermal process, as shown in Fig. The gas absorbs 7000 J of heat as its temperature is increased from 300 K to 1000 K in going from a to b . The quantity of heat ejected by the gas during the process ca is
