The specific heat of gasoline is 2.22 J/g•°C. How much heat would it take to raise 35.0 G of gasoline to 3.00°C?
Olenka [21]
<span>To find the amount of heat energy required to raise a substance by a certain number of degrees, we simply multiply: (specific heat * change in temperature * mass) Heat = 2.22 * 35 * 3 = 233.1 joules Therefore, we would need 233.1 joules of heat to raise the temperature by 3 degrees Celsius.</span>

A sample of an ideal gas has a volume of 0.500 L at 25 degrees celcius and 1.20 atm pressure. What is its volume at 75 degrees c
NemiM [27]
The ideal gas law is PV= nRT.
First you need to manipulate the equation to splice for volume,
Which will be V= nRT/P

Now you need to input the numbers for each variable. Make sure to remember what the value R equals and it’s units. R= 0.08206 L•atm/n•K
