Water Change Lab

Decent Essays

Introduction: Water is a simple molecule created by two hydrogen bonds and one oxygen bond. Water’s formula is H2O because there are two hydrogen bonds and there is one oxygen bond. When these three bonds come together, they become strong and unbreakable. Water is very important. It is important to earth and to your body. Water covers 70% of earth’s surface and your body contains about 60% of water. Water is not just a liquid. Water can also be a solid or gas. Ice is water, but in the form of a solid and a gas is water, but in the form of vapor. Water’s state of matter can change easily due to a temperature increase or decrease. Changing water’s state of matter is a physical change, meaning it can be reversible. So, the objective of this lab is to see how temperature can change water’s state of matter.
Purpose/Problem:
Will the temperature of water continue to rise if heat energy is added to it? What happens to the temperature of water during a change of state?
Hypothesis:
If the temperature is changed, then the water’s state of matter will change because an increase of temperature will form a gas and a decrease of temperature will from a solid.
Materials:
• 1 250 mL. beaker
• Ice
• 1 thermometer
• Hot Plate
• Stopwatch
• Fire-Retardant Glove
• Goggles
Procedures:
1) Gather all materials …show more content…

The hypothesis stated that if the temperature is changed, then the water’s state of matter will change because an increase of temperature will form a gas and a decrease of temperature will from a solid. The hypothesis was correct. The ice started to melt due to the room temperature being hotter than the ice, so it formed a liquid. When the beaker was placed on the hot plate when it was turned on, it made a big temperature change. Due to that temperature change, a gas was formed from a liquid and that liquid use to be a solid. Therefore, temperature changes water’s state of
