The flow ofheat through conduction occurs when fast hot atoms collide with slow cool atoms, transferring some of their kinetic energy in the process.
Solution :
The sun emits = J of energy per second
=
We know,
, where C =
Dividing both sides by 1 second
Then,
Now according to the information, 99.3% hydrogen.
If 0.7 % of hydrogen produce = J of energy per second
Then 1% of hydrogen will produce = J energy per second
So, 100% of hydrogen will produce = J energy per second
= J energy per second
Mass of hydrogen undergo fusion in sun per second
Similarly,
kg
kg
Answer:
The change during the burning of a match stick is a irreversible chemical change while the change when a liquid starts boiling is reversible chemical change.
You Helped Me Lol
Explanation:
There aren't any ions on here, but it will be the ion with a charge of 2+; since electrons have a negative charge, losing one will cause a 1+ charge, losing two will cause a 2+ charge and so on.
Hope this helps :)
The answer would be letter A
