The pressure inside a hydrogen-filled container was 2.10 atmatm at 21 ∘C∘C. What would the pressure be if the container was heated to 93 ∘C∘C ? Express your answer with the appropriate units.

2.61atm

Explanation:

The following were obtained from the question given:

P1 = 2.1atm

T1 = 21°C = 21 + 273 =294K

T2 = 93°C = 93 + 273 = 366K

P2 =?

Using P1/T1 = P2/T2, we can calculate for the new pressure as follows:

P1/T1 = P2/T2

2.1 / 294 = P2 / 366

Cross multiply to express in linear form

294 x P2 = 2.1 x 366

Divide both side by 294

P2 = (2.1 x 366) / 294

P2 = 2.61atm

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
