If it’s hydraulic turbine then it’s potential and kinetic energy and if it’s a thermal process then heat energy from the fuel burnt runs the turbine
Answer:
a mixture of molecules - Box f
atoms of a pure elementa metal - Box D
a solid compound - Box C
a mixture of elements - Box A
Explanation:
Box a has mixture of elements which forms a solid like shape but there are different elements present in the box. The box f has mixture of molecules in which many atoms are combined together. Box c has solid compound with single element.
Answer:
Option (B) 6270J
Explanation:
The following were obtained from the question:
M = 100g
T1 = 30°C
T2 = 45°C
ΔT = 45 —30 = 15°C
C = 4.18J/g°C
Q=?
Q = MCΔT
Q = 100 x 4.18 x 15
Q = 6270J
Therefore, the total amount of heat absorbed is 6270J
