This law states that gas is directly proptional to its temperature. This law is true if the temperature is measured at an absolute scale. The equation for this law is: V1/T1= V2/T2

**Question:** A sample of neon gas occupies a volume of 752ml at 25C. What volume will the gas occupy at 50C if the pressure remains constant? **Given:** V1 of Ne = 752ml T1 of Ne = 25C + 273 = 298K T2 of Ne = 50C + 273 = 323K **Unknown:** V2 of Ne in ml Equation: V1/T1 = V2/T2 V2 = V1T2/T1 V2= (752 ml Ne)(323K) = 242896ml Ne = **//815ml Ne//** _____________ ___________ _____________________      (298K) 298
