A spray can is used until it's empty except for the the propellant gas, which has a pressure of 1344 torr at 23 °c.rnif the can is thrown into a fire (t=475 °c), what will be the pressure in the hot can?rn65 torrrn27,757 torrrn532 torrrn3,400 torr
Accepted Answer
This is a classic example of Gay-Lussac's Law, which states that the pressure of a gas is directly proportional to its absolute temperature when the volume and amount of gas are held constant. Here's how to solve it:
1. Convert Temperatures to Kelvin:
Initial temperature (T1): 23°C + 273.15 = 296.15 K
Final temperature (T2): 475°C + 273.15 = 748.15 K
2. Apply Gay-Lussac's Law:
P1/T1 = P2/T2
P2 = (P1
T2) / T1
P2 = (1344 torr
748.15 K) / 296.15 K
P2 ≈ 3400 torr
Therefore, the pressure in the hot can will be approximately 3,400 torr.
