Question 224165
A completely sealed container contains an essentially ideal gas such as methane. Its initial temperature is 27 degrees celsius (°C). Its initial pressure is 1.0 atm (atmospheres). You heat it to 177°C. What is its pressure at that temperature? 
A. 1atm, B. 0.5atm, C. 1.5atm, D. 2.0atm, E. 6.7atm
--------------
27 C = 300 K
177 C = 450 K
The temperature increased by 50%.
The pressure will increase by 50% also, --> 1.5 atmospheres
