I am currently struggling with a pressure problem that is supposed to be simple, but I spent at least 3 hours on it :

*I also have the answer provided :*A quantity of gas (p = 3 x 105 Pa, T=300K) is compressed until the half of its initial volume and is heated to 70°C. What is the final gas pressure?

What I do not understand is indeed all the way to find this answer...P2=6,86 105Pa

Anyone can please help me ?

Best regards,
