Heat energy is the amount of heat energy in joules gained by a substance when its temperature is raised by 1 degree Celsius per kilogram.
So to find its heat energy we will use the formula Q=mc( delta t)
(NB: im not able to type delta t so to get an idea it is a small triangle with t attached to it indicating change in temperature.
Then we put the values :
Q=(0.026)(500)(22-11)
m_ is mass converted to kilograms
c_ is the specific heat capacity of iron according to Wikipedia it is 500J/kg degree Celsius.
delta t_ is change in temprature
finally we calculate and the answer is
130J .
Answer:
So high-frequency light has photons with high energies and appears blue in color. Thus amplitude and frequency are the two factors that affect the energy transferred by a wave: the height of the wave, and the number of waves passed by each second.
Explanation:
Answer Solid is the state in which matter maintains a fixed volume and shape; liquid is the state in which matter adapts to the shape of its container but varies only slightly in volume; and gas is the state in which matter expands to occupy the volume and shape of its container.
Explanation:
The heat energy released from a piece of wire or any other section of a circuit is:
Energy = (voltage between its ends) x (current through it) x (time it's been going)
