I would see chemical constitution and physical components are not changed.
Because physical reaction won't change the component itself
The pebbles become smooth and even because of erosion. the waves from the sea rub against the pebbles this is erosion. x
Answer: Option (D) is the correct answer.
Explanation:
When heat or energy is transferred through the space in the form of waves or through a material medium then it is know as radiation.
For example, when we take Sun bath then our body gets warm due to solar radiation.
For transfer of heat through radiation it is not necessary that the objects have to in contact with each other.
Thus, we can conclude that out of the given options, the transmission of heat without any contact.
Answer:
N₂ + 3H₂ → 2NH₃
Explanation:
Chemical equation:
N₂ + H₂ → NH₃
Balanced chemical equation:
N₂ + 3H₂ → 2NH₃
Step 1:
N₂ + H₂ → NH₃
left hand side: Right hand side
N = 2 N = 1
H = 2 H = 3
Step 2:
N₂ + 3H₂ → NH₃
left hand side: Right hand side
N = 2 N = 1
H = 6 H = 3
Step 3:
N₂ + 3H₂ → 2NH₃
left hand side: Right hand side
N = 2 N = 2
H = 6 H = 6
Answer:
Heating.
Cooling.
Water Heater.
Washer and Dryer.
Lights.
Refrigerator.
Electric Oven.
Dishwasher.
Charging devices
Explanation:
People use electricity for lighting, heating, cooling, and refrigeration and for operating appliances, computers, electronics, machinery, and public transportation systems.
How it works is a current of electricity is a steady flow of electrons. When electrons move from one place to another, round a circuit, they carry electrical energy from place to place like marching ants carrying leaves. Instead of carrying leaves, electrons carry a tiny amount of electric charge
Hope this helped some!
