Define 1 atm, 1 torr, 1 Pa and 1 bar.

Define 1 Pa-s.

What is 1 torr?

State the relation between atm, Nm, Pa, torr and bar.

1 torr = ……. Pascal

At constant temperature and 1 atm pressure, an ideal gas occupies a volume of 3.25m^(3) . Calculate the final presure of the gas in the units of atm, torr and Pa if the its volume is reduced to 1.25m^(3) while its temperature is kept constant.

A gas is initially at 1 atm pressure. To compress it to 1/4 th of its initial volume, pressure to be applied is: 1 atm, 2 atm, 3 atm, 1/4 atm

1 mmHg= ?___ torr ?
