Two forces that could produce a 30 newton resultant could be: (1) 20 N and 70 N
(2) 10 N and 15 N
(3) 40 N and 5 N
(4) 30 N and 10 N

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation

1. metals

2. metalloids only

3. nonmetals only

4. metals and metalloids

5. metalloids and nonmetals

i just took this assignment so this is correct
