Concept:

Problem: The pressure inside a hydrogen-filled container was 2.10 atm at 21 °C. What would the pressure be if the container was heated to 98 °C?Express your answer with the appropriate units.The ideal gas law (PV = nRT) describes the relationship among pressure P, volume V, temperature T, and molar amount n. When n and V are fixed, the equation can be rearranged to take the following form where k is a constant:PT=nRV=k          or          (PT)initial=(PT)finalWhen n and P are fixed, the expression becomesVT=nRP=k          or          (VT)initial=(VT)final

The pressure inside a hydrogen-filled container was 2.10 atm at 21 °C. What would the pressure be if the container was heated to 98 °C?

The ideal gas law (PV = nRT) describes the relationship among pressure P, volume V, temperature T, and molar amount n. When n and V are fixed, the equation can be rearranged to take the following form where k is a constant:

When n and P are fixed, the expression becomes
