Answer:
Gas cannot melt.
Explanation:
Gas is a state of matter that can only be CONDENSED into a liquid. Solids only can melt.
The total energy of a system remains constant.
Answer:
Rhombic sulphur and monoclinic sulphur.
It shifts and the temperature changes I think hope this helps
Given parameters:
Heat of fusion of water = 334j/g
Mass of ice = 45g
Temperature of ice = 0.0°c
Unknown:
Amount of heat needed to melt = ?
Solution:
This is simply a phase change and a latent heat is required in this process.
To solve this problem; use the mathematical expression below;
H = mL
where m is the mass
L is the heat of fusion of water;
H = 45 x 334 = 15030J
