# You have 3.5 L of NO at a temperature of 22.0 °C. What volume would the NO occupy at 37 °C? (Assume the pressure is constant.)

Interpretation Introduction

Interpretation:

The new volume of NOat37°C has to be found out. Given that the initial volume is 3.5 L and temperature is 22°C

Concept Introduction:

Charles’s law: States that volume is directly proportional to temperature when the gas is held at constant pressure and number of molecules.

VTV=constant×TV1T1=V2T2

Explanation

The new volume of the gas when the temperature changes from 22â€‰Â°Câ€‰toâ€‰37â€‰Â°C can be calculated as,

Given data:

â€‚Â V1â€‰â€‰=â€‰â€‰3.5â€‰LT1â€‰â€‰â€‰=â€‰â€‰22Â°Câ€‰â€‰â€‰â€‰â€‰â€‰â€‰=â€‰â€‰22â€‰+â€‰273â€‰=â€‰295â€‰KT2â€‰â€‰â€‰=â€‰37Â°Câ€‰â€‰â€‰â€‰â€‰â€‰â€‰â€‰=â€‰â€‰37â€‰+â€‰273=â€‰310â€‰
