Question

A football is inflated to 12psi at 20°C What is the new pressure in the football

when the temperature is lowered to -5C

Answer 1

Answer: The new pressure is 3 psi.

Step-by-step explanation:

Given:
`P_(1)` = 12 psi,
`T_(1) = 20^(o)C`

`P_(2)` = ?,
`T_(2) = 5^(o)C`

Formula used is as follows.

`(P_(1))/(T_(1)) = (P_(2))/(T_(2))\\(12 psi)/(20^(o)C) = (P_(2))/(5^(o)C)\\P_(2) = (12 psi * 5^(o)C)/(20^(o)C)\\= 3 psi`

Thus, we can conclude that the new pressure is 3 psi.
