matty questioned:

A fastidious gasoline engine has an efficiency of 30%; that is, it converts into helpful work 30% of the heat generated by burning a fuel. If the engine consumes 0.80 L/h of a gasoline with a heating regard of 3.5 x 104 kJ/L, how much potential does it grant? Express the pledge both in kW and horsepower.

Thankfulness for anyone who can help!

What physically causes gas pressure and how can you increase the pressure of gas?

Jenn questioned:

Also, I have a few additional questions that I would like answered too Thankfulness for all your help.

1. How do temperatures in Celsius and Kelvin clash in their relationship with pressure?

2. How do you enter an equation to express the relationship between pressure and like (K). Use secret code P, T, and c.

3. What must take place to the pressure of gas if Kelvin is doubled?

4. What shoul be the pressure at “pledge zero”

Thankfulness!
