Answer:
D. lightning !!
Explanation:
This is the only answer that makes sense. none of the other answers are anywhere near electrical energy. Lightning is a discharge of the static electricity built up in the atmosphere. The energy is transferred to the ground in the form of an electrical arc. :)
Answer:
There are significant environmental impacts associated with coal mining and use. It could require the removal of massive amounts of top soil, leading to erosion, loss of habitat and pollution. Coal mining causes acid mine drainage, which causes heavy metals to dissolve and seep into ground and surface water.

Explanation:
The children feel cold on touching the ice block as the temperature of it is much less than body temperature.
Answer:
T₂ = 800 K
Explanation:
Given that,
Initial temperature of the gas, T₁ = 127°C = 400 K
Initial volume, V₁ = 10 L
Final volume, V₂ = 20 L
We need to find the new temperature.
The volume of a gas is directly proportional to its Kelvin temperature.
Let T₂ is the new temperature. So,
![\dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}\\\\T_2=\dfrac{V_2T_1}{V_1}\\\\T_2=\dfrac{20\times 400}{10}\\\\T_2=800\ K](https://tex.z-dn.net/?f=%5Cdfrac%7BV_1%7D%7BT_1%7D%3D%5Cdfrac%7BV_2%7D%7BT_2%7D%5C%5C%5C%5CT_2%3D%5Cdfrac%7BV_2T_1%7D%7BV_1%7D%5C%5C%5C%5CT_2%3D%5Cdfrac%7B20%5Ctimes%20400%7D%7B10%7D%5C%5C%5C%5CT_2%3D800%5C%20K)
So, the new temperature of the gas is 800 K.
