Questions and Answers

What does Charles's Law indicate about the relationship between volume and temperature of a gas at constant pressure?

Volume increases as temperature increases. (correct)

Volume decreases as temperature increases.

Volume increases as temperature decreases.

Volume is independent of temperature.

Which mathematical equation correctly represents Charles's Law?

V = T + 273.15

V/T = constant (correct)

V = constant / T

V/T = constant * P

When converting Celsius to Kelvin, which of the following formulas should be used?

T(K) = t (°C) - 273.15

T(K) = t (°C) + 273.15 (correct)

T(K) = t (°C) * 273.15

T(K) = t (°C) + 100
