Question

Q1) (a) The latent heat of vapourisation of heat________ (b) The latent heat of fusion of ice in __________

Q2) "Sublimation does not require heating" Explain?

Q3) Write the other 2 states of matter?

No spam plz dear​

Answer 1

Answer:

1.(a) 2260kJ/kg (or) 40.8 kJ/mol

(b) 80cal/gram

2. Yes, it is true that sublimation does not require heating. Sublimation is a process of conversion of solid into vapour state and vapour into solid state. And this happens not because of heat it is a natural phenomenon as it gains the heatfrom the surface.

3.states of matter: solids, liquids,gas and plasma.

hope it is helpful to you

thank you.

1) The latent heat of vapourisation of heat

Condensation

2) Yes it is true that sublimation does not require heating . Sublimation is a process of conversion of solid into vapor state and vapour into solid state without coming in liquid state. ... And this happens not because of heat it is a natural phenomenon as it gains the heat from the surface .

3) Solid is the state in which matter maintains a fixed volume and shape; liquid is the state in which matter adapts to the shape of its container but varies only slightly in volume; and gas is the state in which matter expands to occupy the volume and shape of its container.
