1. Which phase change is accompanied by the release of heat? A) H20(s)--> H2O(g) B) H20(l) ->H2O(s) C) H20(l)→ H2O(g) D) H2O(s) -> H20(l)​

Respuesta :

Answer:

B, liquid to solid.

Explanation: Since heat is being released, the particles for H2O would clump up. Heat is basically being taken out.

The phase change which is accompanied by the release of heat is: B) [tex]H_20_{(l)} -->H_20_{(s)}[/tex].

Matter can be defined as anything that has mass and can occupy space.

Since matter are made up of atoms, they have a property of existing in three (3) distinct phase (state) and these include;

  • Solid.
  • Gas.
  • Liquid.

A phase change can be defined as a change from a particular phase (state) without a corresponding change in the chemical composition of a substance (matter).

Generally, matter changes phase (state) when heat (thermal) energy is either released or absorbed, with a corresponding change in its absolute temperature.

Basically, the two phase changes where heat (thermal) energy is released are:

I. Condensation: gas to liquid.

II. Freezing: liquid to solid.

In conclusion, the freezing of liquid water to solid is a phase change that is typically accompanied by the release of heat (thermal) energy.
