Question

At 127°C temperature volume of gas is 3 L. If volume of gas becomes half then calculate
temperature. Pressure is 1 bar.​

Answer 1

Answer:

First, understand that Celsius and Kelvin degrees are the same size. The difference is that the Celsius scale starts with 0 as the freezing point of water, whereas Kelvin scale starts with 0 assigned to “absolute zero” (about -273(C)).

So first convert your Celsius value of 127 to Kelvin degrees (by adding 273).

Now take 1/5 of that value. That is your answer in deg(K).

To convert back to deg(C) simply subtract 273

Answer 2

Answer:

T2 = 200K

Explanation:

T1 = 127C + 273K = 400K

V1 = 3L

V2 = 3/2 L

T2 = ???

We know that,

∴ V1/T1 = V2/T2

∴ 3/400 = 3/2*T2

∴ T2 = 3*400/(2*3)

∴ T2 = 200K
