| **If, when a gas was heated in a closed vessel by 140 K, its pressure increased 1.5 times, then what was the initial temperature of the gas?**

Given:

Delta T = 140 K;

P2 = 1.5 P1.

Find: T.

Decision:

Let’s make a proportion that will help us find T.

P1 / T = P2 / T + delta T.

Let’s transform:

1 / T = 1.5 / T + delta T.

From this we get 0.5 T = delta T.

We find T, since T = 2 * delta T, it turns out that T = 2 * 140 = 280 K.

Answer: 280
