Question

The volume of a gas is 0.40 L at 30.0°C. If the temperature is increased to 50.0°C, what is the new volume of the gas according to Charles's Law?

a) 0.426 mL
b) 0.600 mL
c) 0.375 mL
d) 0.400 mL

Answer 1

According to Charles's Law, the volume of a gas is directly proportional to its temperature at constant pressure. To find the new volume, we can use the formula V2 = V1 × (T2 / T1), where V1 is the initial volume, T1 is the initial temperature, T2 is the new temperature, and V2 is the new volume. Plugging in the values, we get: V2 = 0.40 L × (50.0°C + 273.15) / (30.0°C + 273.15) = 0.426 L. Therefore, the new volume of the gas according to Charles's Law is 0.426 mL (option a).

Step-by-step explanation:

According to Charles's Law, the volume of a gas is directly proportional to its temperature at constant pressure. To find the new volume, we can use the formula V2 = V1 × (T2 / T1), where V1 is the initial volume, T1 is the initial temperature, T2 is the new temperature, and V2 is the new volume. Plugging in the values, we get:

V2 = 0.40 L × (50.0°C + 273.15) / (30.0°C + 273.15) = 0.426 L

Therefore, the new volume of the gas according to Charles's Law is 0.426 mL (option a).
