A sample of nitrogen gas has a volume of 5.0 ml at a pressure of 1.50 atm. what is the pressure exerted by the gas if the volume
olchik [2.2K]

A sample of nitrogen gas has a volume of 5.0 ml at a pressure of 1.50 atm. what is the pressure exerted by the gas if the volume increases to 30.0 ml, at constant temperature is 0.25atm.

On constant temperature, the pressure and volume relation become constant before and after the change in quantitities have occurred.

According to Boyle's Law,

P₁V₁ = P₂V₂

where, P₁ is pressure exerted by the gas initially

V₁ is the volume of gas initially

P₂ is pressure exerted by the gas finally

V₂ is the volume of gas finally

Given,

P₁ = 1.5 atm

V₁ = 5 ml

V₂ = 30 ml

P₂ =?

On substituting the given values in the above equation:

P₁V₁ = P₂V₂

1.5 atm × 5 ml = P₂ × 30 ml

P₂ = 0.25 atm

Hence, pressure exerted by the gas is 0.25atm.

Hot rolled steel is generallythan cold drawn steel stronger b) weaker c. more fatigue tolerant d. tougher ar ield streneth 350 M
Burka [1]

Answer:

b) weaker

Explanation:

Hot rolled steel is generally weaker than the cold drawn steel. The yielding stress of cold rolled steel is higher than than hot rolled steel. At the same time the crystal structure remain the same in cold rolled steel. Giving it a better surface finish and closer tolerances. The strength and hardness of a cold roll steel is higher than  the hot rolled steel
