Answer:
first blank is chemical second blank is kinetic energy
Answer:
W = 8.01 × 10^(-17) [J]
Explanation:
To solve this problem we need to know the electron is a subatomic particle with a negative elementary electrical charge (-1,602 × 10-19 C), The expression to calculate the work is given by:
W = q*V
where:
q = charge = 1,602 × 10^(-19) [C]
V = voltage = 500 [V]
W = work [J]
W = 1,602 × 10^(-19) * 500
W = 8.01 × 10^(-17) [J]
So the air evaporate s and mix the temptures and marks air power to the same theme as the other the two degrees lower and lower until they are the same
Answer:
The heat is 10458 J and 15480 J.
Explanation:
Given that,
Temperature T₁ = 404 K
Temperature T₂ = 298 K
Work done = 2740 J
If the temperature T₁ =298 k
Temperature T₂ = 245 K
We need to calculate the heat
Using efficiency formula
...(I)
We need to calculate the efficiency
Using formula of efficiency



Put the value of efficiency in equation (I)



Again, we need to calculate the efficiency



We need to calculate the heat
Using equation (I)


Hence, The heat is 10458 J and 15480 J.
