Answer:
The heat lost by the water
3.8 KJ
The heat gain by ice
= 228.76 J
The heat required to melt the ice
= 3340 J
Explanation:
Mass of ice cube
= 10 gm
Initial temperature of ice cube
= 0 °c
Mass of water
= 100 gm
Initial temperature of water
= 20 °c
Final temperature of mixture
= 10.93 °c
(a). Total heat lost by the water
(
-
)
⇒
100 × 4.184 (20 - 10.93)
⇒
3.8 KJ
This is the heat lost by the water.
(b). Heat gained by the ice cube
=

⇒
= 10 × 2.093 × ( 10.93 - 0)
⇒
= 228.76 J
This is the heat gain by ice.
(C). Heat required to melt the ice
=
× Latent Heat
⇒
= 10 × 334
⇒
= 3340 J
This is the heat required to melt the ice.
I'm pretty sure the answer is B double check to make sure it isn't A
Answer: 0.156 mol
Explanation:
To find the moles of 17.2 g K₂S, we need to know the molar mass to convert.

Answer:
Due to the decrease in the gravitational force, it will take longer time for ball to reach the ground while dribbling. Moreover, the hang time of players will also be longer. This means that the players will stay on air longer and will be able to jump higher.
