The volume (V) of a mass of gas varies directly as its absulute temperature (T) and iversely as the pressure (P) applied to it. The gas occupies a volume of 400 ml when the temperature is 150 k and pressure is 240 Pa. what is the temperature of gas whose volume and pressure are 250 ml and 320 Pa respectively?

Emperical formula of compound is `SF_(4)`. At `27^(@)C` 0.1gm of gaseous compound occupies a volume of 22.2 ml and exert a pressure 1 atm. What is mol
PV=nRT M.F= `(SF_(4))_(x)` `(1.02)xx22xx10^(-3)` `(0.1)/((108)x)xx0.0821xx293` `x=(0.1xx0.0821xx293)/((108)(1.02)(22.1)xx10^(-3))=1` M.F. `=SF_(4)`

A liquid occupies a volume of 2 × 10^-4 m^3 at 0 °C. Calculate the increase in its volume If It is heated to 80 °C.
Given: V0 = 2 × 10-4 m3, T0 = 0°C,T = 80°C, γr = 4 × 10-4 K-1, T – T0 = 80 – 0 = 80°C To find: Increase in volume (∆V) Formula: ∆V = V0γr(T – T0) Calculation: From formula. ∆V =...
