I just took the test and got it right
Answer:
D) All of the above
Explanation:
When the temperature increases, it means that the kinetic energy of the gas molecules had increased too because the temperature is a way to measure this kinetic energy. When this happens, the velocity of gas molecules increases because kinetic energy and velocity are directed related:
Where <em>Ek</em> is the kinetic energy, <em>m</em> is the mass and <em>v</em> is the velocity.
If the velocity increases, there will be more collisions between molecules, so, with more collisions, the pressure, which is the measure of the force a gas makes in the system, will increase. So, all the answers explain why the pressure of a gas increases when the temperature increases.
Answer:
The answer to your question is Qt = 15750 cal
Explanation:
Data
mass = m = 150 g
Initial temperature = T1 = 0°C
Final temperature = T2 = 25°C
Process
1.- Calculate the Latent heat of fusion
Latent heat of fusion for water = l = 80 cal/g
Heat = Q
Formula
Q = ml
Substitution
Q = (150)(80)
Simplification and result
Q = 12000 cal
2.- Calculate the Specific heat
Specific heat of water = C = 1 cal/g°C
Formula
Q = mCΔT
Substitution
Q = (150)(1)(25 - 0)
Simplification and result
Q = 3750 cal
3.- Calculate the total heat
Qt = 12000 + 3750
Qt = 15750 cal
