Unformatted text preview: What will be the gas pressure when the temperature changes to 450 K? P 1 = 1.5 atm P 2 = ? T 1 = 320 K T 2 = 450 K P 1 = P 2 T 1 T 2 P 2 = P 1 T 2 = 1.5 atm x 450 K = 2.1 atm T 1 320 K 1pt 5. What is inverse relationship? As one variable increases the other decreases or as one variable decreases the other increases. For example in Boyles law which is an inverse relationship as pressure increases, volume decreases 1pt 6.
