Answer 3

Question 19.19 would be II only. (The molecular average Ke of A is higher than that of B.)

Answer 4

1.1= true because heat is kinetic energy and thus the temperature is dependent on heat.
2.2 false because the temperature is kintetic energy. degrees Kelvin is the particles moving and colliding.
3.3 you were right 2.
4.4. true
5.5 false
6.6 is false. specific heat varies with different substances
7.7 is correct. because u ot 36000 j/ by the change in temp which is 25.. so you just figured out that 1440 j is the energy change per temperature. 1440 per Degree C you/ by 13.5 g which gives u 1.05*10^2
