Answer:
I think it would be the last answer
Explanation:
Answer:
It is a physical change because this change is reversible and no chemical reaction occurs.
Explanation:
In an endothermic reaction, the heat in going in. it absorbs energy from its surroundings.
hope this helps!
PV=nRT
P = 85.0 x 10^3 Pa
T = 273 + 20 = 293 K
n = 2.0 moles
R = 8.314 m3. pa / mol .K
V = 2.0 x 293 x 8.314 / 85.0x10^3 = 0.195623529 m^3
