Asample of o2 occupies a volume of 600 ml. if the pressure exerted on the o2 is tripled with the temperature remaining constant, the new volume of the oxygen is

For 1 mole of an ideal gas, we have PV=RT............(Eq. 1)
where, P = pressure
V= volume
R = universal gas constant
T = Temperature

Let, P1, V1 and T1 be initial pressure, volume and temperature of  respectively

Let, P2, V2 and T2 be pressure, volume and temperature of respectively, after application of pressure.

Using Eq. 1 we get,  ....... (Eq. 2)

Now, since that T1=T2 and P2=3(P1)

∴ Eq. 2 becomes P1V1=P2V2
∴ 
∴ V2 =  V1

Thus, final volume V2 will be 1/3 of initial volume V1

Ans. : frostbite is when exposure to cold temperatures causes freezing to the skin or other tissues. it most commonly affects the hands, feet, and face. the longer areas are exposed to cold, typically the worse the frostbite. the water temperature used for rewarming a frostbitten part should be : (102 -105) f degrees.
