I don't understand this assignment, my brain wont let me understand the letters. I'd really appreciate some help, ill give brainliest
1. The ideal gas law is PV = nRT. Explain what each variable is in this equation and include a common unit used to measure that variable

What happens to the remaining quantities

2. Pressure (P) (doubles / halves / stays constant )
3. Volume (V) (doubles / halves / stays constant )
4. Moles (n) (doubles / halves / stays constant )
5. Gas constant (R) (doubles / halves / stays constant )
6. Temperature (T) (doubles / halves / stays constant )
