Cycles ch 3 Water

The three states of water are:

1. Solid (ice)
2. Liquid (water)
3. Gas (water vapor)

Water changes state through the following processes:

1. Melting: Ice (solid) turns into water (liquid) when heated.
2. Freezing: Water (liquid) turns into ice (solid) when cooled.
3. Evaporation: Water (liquid) turns into water vapor (gas) when heated.
4. Condensation: Water vapor (gas) turns back into water (liquid) when cooled.

The rate of evaporation is affected by several factors:

• Temperature: Higher temperatures increase evaporation rates.
• Surface Area: Larger surface areas allow more molecules to escape.
• Air Movement: Wind or air movement can carry away vapor, increasing evaporation.
• Humidity: Lower humidity levels increase evaporation rates as the air can hold more water vapor.

Ice is a solid state of matter, characterized by a fixed shape and volume.

The three states of water are:

1. Solid - Examples include ice and snow.
2. Liquid - This includes the water we drink and use daily.
3. Gaseous - This includes water vapor and steam, both of which are invisible.

The process is called freezing.

Water freezes at 0°C.

When water is placed in a freezer, it loses heat and its temperature decreases, leading to the formation of ice at 0°C.

The freezing point of water is 0°C.

The process is called melting.

Ice melts at 0°C.

The melting point of ice is 0°C.

When ice gains heat, its temperature increases and it changes from solid to liquid state, a process known as melting.

Factors that can affect how quickly ice melts include temperature, surface area, and the presence of substances like salt or sugar.
