The best answer is simply human error or being in a area where the environment could have an impact on your result.
Materials that are good conductors of thermal energy are called thermal conductors. Metals are especially good thermal conductors because they have freely moving electrons that can transfer thermal energy quickly and easily
Answer:Sunlight travels through space without the aid of fluids or solids
Explanation: Radiation involves transfer of energy or heat with the help of electromagnetic waves.
For example, radiations from Sun help in transfer of energy or heating of object on which it falls. Like, when radiations are falling on a metal rod then after sometime the rod becomes hot due to absorption of radiations from the Sun.
Answer:
option c
Explanation:
E = hf
E= energy
h = Planck constant
f = frequency
E = 6.6 X 10^-34 X 4 X 10^14
E = 2.64 X 10^-19J
