Question

When 200 ml of a gas at constant pressure is heated from 0 °C to 100°C, the volume must be multiplied by:-

Answer 1

Answer:

length breath area what

Answer 2

The final voulme is 1.36 times the initial volume.

Explanation:

Given that the pressure is constant

Let us assume that the gas is ideal.

i.e, it obeys PV = nRT

where, P= pressure

V= volume of gas

n= number of moles

R= universal gas constant

T= temperature in kelvin.

since P, R, n don'T change,

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$

T₁ =0+273 = 273 K

T₂=100+273= 373 K

i.e, V₂= V₁($\frac{373}{273}$)

i.e It must be multiplied by $\frac{373}{273}$=1.36
