Question

The gases in a can are at a temperature of 27 °C and a pressure of 30 kPa. If the gases in the can reach a pressure of 90 kPa, the can will explode. To what temperature must the gases be raised in order for the can to explode?

Answer 1

Answer:

60०c gases can temperature

Answer 2

Correct option is

A

177
