Kyle has been keeping his eye on a sound system that costs x dollars. the system goes on sale for 15% off the regular price. which expression can kyle use to find the sale price? a) .85x b) 1 + .15(x) c) x − .15 d) 1 − .15(x)

the initial temperature is 22.5 atm

Step-by-step explanation:

The law describing pressure-temperature relationship is the Gay-Lussac's Law.

The Mathematical Form of which is:

=>

Where P1 = ? , P2 = 30 atm, T1 = 600 K and T2 = 800 K

=>

=> P1 = 0.0375 * 600

=> P1 = 22.5 atm

So, the initial temperature is 22.5 atm
