Why can a gas be compressed to any extent?

An ideal gas is compressed at a constant temperature, will its internal energy increase or decrease?

When 1 mol of an ideal gas is compressed in a reversible isothermal process at T K, the pressure of the gas changes from 1 atm to 10 atm. In the process, if the work done by the gas be 5.744kJ, then T is-

Why can't you able to compress a wooden block?

Some amount of gas is compressed at STP in an (ii) isothermal process in such a way that the final volume of the gas becomes 1/5 times the initial volume. What will be the final temperature and pressure of the gas in the case? (gamma = 1.4 for the gas)

An ideal gas is compressed adiabatically to 1/4 th of its initial volume at 10^(@)C . Find out the final temperature of the gas [gamma = 1.4] .

A gas is compressed isothermally to half its initial volume. The same gas is compressed separately through an adiabatic process until its volume is again reduced to half. Then

A gas is compressed by an external pressure of 5 atm. The work done in the process is 1034 J. How much volume of the gas is reduced?

What will the value of compressibility factor (Z) be for a gas if the pressure correction term in the van der waals equation for the gas is neglected?
