A gas occupies 200ml at a temperature of 26 degrees Celsius and 76mmHg pressure. Find the volume at -3degree Celsius with the pressure remaining constant.

184.62 ml

Explanation:

Let and be the initial and and be the final pressure, volume, and temperature of the gas respectively.

Given that the pressure remains constant, so

...(i)

= 200 ml

K

K

From the ideal gas equation, pv=mRT

Where p is the pressure, v is the volume, T is the temperature in Kelvin, m is the mass of air in kg, R is the specific gas constant.

For the initial condition,

For the final condition,

Equating equation (i), and (ii)

 [from equation (i)]

Putting all the given values, we have

Hence, the volume of the gas at 3 degrees Celsius is 184.62 ml.

it should be all of them because it asks if you included all of those in your answer
