Answer:
The kinetic theory of matter explains that all matter is made of particles which are constantly moving/have energy. The energy varies depending on the temperature of the matter, therefore determining if the matter is solid, liquid, or gas. When the energy of a particle is increased or decreased, a phase change can occur.
Answer:
893K=620 °C
Explanation:
PV=nRT
P=nRT/V
P= (1 mol* 0.0821* 298K)/15L P=1.63 atm
T=PV/nR
T=(1.63 atm*45 L)/(1 mol*0.0821)
T= 893K=620 °C
