Question

Pressure cookers allow food to cook faster because the higher pressure inside the pressure cooker increases the boiling temperature of water. A particular pressure cooker has a safety valve that is set to vent steam if the pressure exceeds 3.4 atm. What is the approximate maximum temperature that can be reached inside this pressure cooker

Answer 1

Answer:

8.18K

Explanation:

This question is solved using the ideal gas equation:

PV=nRT

where,

P= pressure

V= volume

n= no. of moles

R= gas constant(8.314 J/K/mol)

T= temperature

Since in the question, volume of the container and amount of gas is not given,we'll assume a value for these variables and substitute it in our formula;

P= 3.4 atm

V= 1 litre (assumption)

n= 5 moles (assumption)

R= 8.314

T= ?

PV=nRT

3.4*1=5*8.314*T

T=3.4*1/0.08314*5

T= 8.18K
