The pressure inside a hydrogen-filled container was 2.10 atm at 21 ∘C. What would the pressure be if the container was heated to 95 ∘C ? Express your answer with the appropriate units.

The new pressure is 2.63 atm

Explanation:

Step 1: Data given

Pressure in the hydrogen filled container = 2.10 atm

The temperature = 21 °C = 294 K

The temperature is increased to 95 °C = 368 K

Step 2: Calculate the new pressure

P1/T1 = P2/T2

⇒with P1 = the initial pressure = 2.10 atm

⇒with T1 = the initial temperature = 21 °C = 294 K

⇒with P2 = the final pressure = TO BE DETERMINED

⇒with T2 = the final temperature = 95.0 °C = 368 K

2.10 atm / 294 K = P2 / 368 K

P2 = 2.63 atm

The new pressure is 2.63 atm

c is the answer because when something is left after something evaporates that shows the chemical change.
