Question

A given mass of gas in a rigid container

is heated from 100°C to 500°C. Which of the following responses best describes what will happen to the pressure of the

(a) The pressure will decrease by a factor of five.

(b) The pressure will increase by a factor of five.

(c) The pressure will increase by a factor of about two

(d) The pressure will increase by a factor of about eight.

(e) The pressure will increase by a factor of about twenty-five.​

Answer 1

Answer:

The answer is (b).

Explanation:

When volume is constant, pressure is directly proportional to temperature.

Answer 2

Answer:

(Option-B)  The pressure of the gas increase by a factor of five.

Explanation:

Given that a certain mass of gas is heated from 100°C to 500°C i.e. the temperature of the gas is increased by five times.

In the process of heating the volume and number of moles of gas remains constant as given in the question.

Using the ideal gas equation,

PV=nRT

As temperature is increased by 5 times, then pressure will also get increased by 5 times.
