Answer:
=10 joules
when multiplying with newtons ( the unit of force)
by a perimeter, it will becone joules, but the specific amount depends on how many newtons and metres there are
Answer:
c. 216 g
Explanation:
There is actually 215.852304 but when you round it, you will get 216
The heat energy required to change a unit mass of a solid into a liquid at constant temperature is called thermal equilibrium.
'Equilibrium' means balance, and thermal is used to define temperature.
The mass of solute will dissolve in 100g of water at the following temperatures will be 153 gms, 40 gms, 70gms simultaneously.
<h3>How dissolution of solute is affected by temperature ?</h3>
On increasing temperature the amount of solute for dissolution decreases.
It is independent of the nature of solute.
Hence,
- KNO₃ at 70degree = 153 gms
- NaCl at 100 degree = 40 gms
- NH₄Cl at 90 degree = 70gms

Look it up on the periodic table i attached below
im too lazy to type that all out im sorry but this is one of the easiest things you'll do in chemistry and if you tried you could actually finish all 5 of these in less than a minute instead of taking like 10 min to type 10 problems out separately and making 4 diff posts
