Question

If a gas at 35°C and 2.3 atm is heated to 50°C, then what will the new pressure be? (Gay Lussac's Law)

Remember to convert Celsius tempertature into Kelvin. (Take the Celsius values and add 273)

Answer 1

THE NEW PRESSURE OF THE GAS AT 50 °C IS 2.41 atm.

Step-by-step explanation:

Initial temperature = 35 °C = 35 + 273 K= 308 K

Final temperature = 50 °C =50 + 273 K = 323 K

Initial pressure = 2.3 atm

Final pressure = unknown

Using the combined gas equation to get the relationship between pressure and temperature for a given gas sample, we have;

P1 / T1 = P2 / T2

P2 = P1 T2 / T1

P2 = 2.3 * 323 / 308

P2 = 742.9 /308

P2 = 2.41 atm.

THE NEW PRESSURE IS 2.41 atm at 50 °C
