Answer:
water evaporates from the ocean into atmosphere. water vapour condenses to form clouds. clouds produce rain. rainwater needed for plant growth.
Explanation:
Answer: D
Explanation: Convection transfers heat by movement such as air and water.
Answer:
The pond has more energy because I is so much larger that the Cup of boiling water. Since that mass of the pond is so much larger, It is generating more energy than a boiling cup of water.
Friction actually generated friction because you create charges that are dealing with electricity. When you rub some against each other , you can create a little spark which is electricity . Friction can produce static or something because it can be transferred by two or more items .
Answer:
NO2 is the molecular formula of nitrogen Oxide
Explanation:
Correct question
An oxide of nitrogen contain its own volume of nitrogen
its vapour dentity is 23. Find the molecular formula
Of nitrogen Oxide
Solution
As we know
Molecular Weight is equal to two times the vapour density
Hence, the molecular weight of Oxide of nitrogen is 2 * 22 = 44
Molecular weight of Oxide of nitrogen is the sum of atomic weight of nitrogen and oxygen
Molecular weight of Oxide of nitrogen = 14 + 16 *Y
14 + 16 *Y = 46
Y = 2
Hence, the formula is NO2
