## What is conduction kid definition?

Conduction transfers heat within a body or between two bodies that are touching. It is a point-by-point process of heat transfer. Conduction occurs in solids, liquids, or gases that are at rest.

## What is boiling point of water?

212°F (100°C)Water / Boiling point

Which section of the graph indicates the boiling point?

The plateaus or horizontal lines on the graph represent the transition between states of the sample. The first plateau represents the melting (or transition from solid to liquid) and the second plateau represents boiling (or transition from liquid to gas).

### What is vapour pressure curve?

A vapor pressure curve is a graph of vapor pressure as a function of temperature. To find the normal boiling point of liquid, a horizontal line is drawn from the y-axis at a pressure equal to standard pressure.

### Where is vapor pressure on a phase diagram?

The line that connects points A and B is the vapor pressure curve of the liquid, which we discussed in Section 11.5. It ends at the critical point, beyond which the substance exists as a supercritical fluid. The line that connects points A and C is the vapor pressure curve of the solid phase.

Which method of thermal energy transfer occurs in a solid by means of atomic and molecular vibrations within the material?

conduction
Heat is transferred by conduction when adjacent atoms vibrate against one another, or as electrons move from one atom to another. Conduction is the most significant means of heat transfer within a solid or between solid objects in thermal contact.

#### What is freezing science?

Freezing refers to the phase change of a substance from the liquid state to a solid-state. This is a phase change phenomenon which means that a substance is transformed from one state of matter to another state.

#### What is gas vapor pressure?

Vapour pressure is a measure of the tendency of a material to change into the gaseous or vapour state, and it increases with temperature. The temperature at which the vapour pressure at the surface of a liquid becomes equal to the pressure exerted by the surroundings is called the boiling point of the liquid.

How do you analyze melting point?

The melting point of an organic solid can be determined by introducing a tiny amount into a small capillary tube, attaching this to the stem of a thermometer centred in a heating bath, heating the bath slowly, and observing the temperatures at which melting begins and is complete.

## How are melting and boiling points determined from a phase diagram?

The normal melting and boiling points are those when the pressure is 1 atmosphere. These can be found from the phase diagram by drawing a line across at 1 atmosphere pressure.

## What is fusion curve?

Fusion(melting) (or freezing) curve – the curve on a phase diagram which represents the transition between liquid and solid states. Vaporization (or condensation) curve – the curve on a phase diagram which represents the transition between gaseous and liquid states.

What is sublimation curve?

triple point is called the sublimation curve. It represents the equilibrium between solid and gas, and when the sublimation curve is crossed, the substance changes directly from solid to gas.

### What do the curved lines on a phase diagram represent?

The curved lines represent conditions of pressure and temperature at which two phases exist in equilibrium.
