Question

To what temperature should 2.3L of a gas at 25°C be heated in order to expand its volume under constant pressure?

a) 273.15°C
b) 298.15°C
c) 325.47°C
d) 350.68°C

Answer 1

To expand the volume of the gas at constant pressure, it should be heated to 298.15°C.

Step-by-step explanation:

The question asks about the temperature at which a gas should be heated in order to expand its volume under constant pressure. This can be solved using Charles's Law, which states that the volume of a gas is directly proportional to its temperature, assuming constant pressure. To calculate the temperature, we can use the formula:

V1/T1 = V2/T2

Given the initial volume (V1 = 2.3L) and temperature (T1 = 25°C), we can rearrange the formula to solve for T2:

T2 = T1 * (V2/V1)

Substituting the given volume (V2 = 2.3L) and rearranging:

T2 = 25°C * (2.3L/2.3L)

T2 = 25°C

Therefore, the answer is option b) 298.15°C.
