**Problem Statement:**Air enters a hot-air furnace at 7°C and leaves at 77°C. If the pressure does not change, each entering cubic meter of air expands to _____________.**Options:**A. 0.80 m³ B. 1.25 m³ C. 1.9 m³ D. 7.0 m³ E. 11 m³ F. None of the above **Explanation:**Using the principles of thermodynamics, specifically Charles's Law which states that at constant pressure, the volume of a gas is directly proportional to its temperature in Kelvin, you can solve this problem.

Given: The initial temperature of the gas is 7° C. The final temperature of the gas is 77° C. The initial volume of the gas is 1 m3. Introduction: When the pressure of the system is kept constant then the volume of the gas is directly proportional to the temperature of the gas. This is called Charle's law.Calculation: Write the expression for Charle's law for the gases. V1T1=V2T2 Here, V1, T1 is the initial volume and temperature respectively and V2, T2 is the final volume and temperature respectively. Substitute, 7° C for T1, 77° C for T2 and 1 m3 for V1 in the above expression. 1 m37+273K=V277+273KV2=350 K1 m3280 KV2=1.25 m3 Thus, option B is correct.
