Answer:
20°C
Explanation:
Heat gained by the colder water = heat lost by the warmer water
m₁ C (T − T₁) = m₂ C (T₂ − T)
m₁ (T − T₁) = m₂ (T₂ − T)
(500) (T − 10) = (100) (70 − T)
5 (T − 10) = 70 − T
5T − 50 = 70 − T
6T = 120
T = 20
The final temperature is 20°C.
I believe the answer is true
It's like a a magnetic wave, it'll bounce off.
Mass of methanol = 1.922g; Change in temperature = 5.14° C; Heat capacity of the bomb calorimeter + water = 8.69kJ/°C. Number of moles.
Ok here's a rough image of how a typical energy diagram works. You give a little energy (A) and you get the potential that was in there all along. Kinda like pushing a big rock off a cliff. You do a little work then get a lot of energy out as the PE turns into other forms. In a match it's heat and light
