Thermal Properties of Water: Experiment on Obtaining Temperature-Time Graph of Melting Ice

The video tutorial explores the thermal properties of water through an experiment to observe the melting of ice. The experiment involves placing crushed ice in a boiling tube within a beaker of water, which is heated slowly. The temperature of the ice is monitored every 30 seconds to create a temperature-time graph. The results show that the temperature remains constant at 0°C while the ice melts, demonstrating the latent heat of fusion. The video concludes with a discussion on the significance of the findings and the behavior of ice as it transitions to liquid water.

What is the main purpose of placing the boiling tube with crushed ice in a beaker of water?

• To slow down the melting process

• To speed up the melting process

• To increase the temperature of the ice

• To prevent the ice from melting

Why is it important for Matt to wear safety spectacles during the experiment?

• To shield his eyes from the Bunsen burner

• To enhance visibility

• To protect against corrosive chemicals

• To prevent ice from splashing

At what temperature does the experiment start recording the temperature of the ice?

• 2 degrees centigrade

• 0 degrees centigrade

• -10 degrees centigrade

• -5 degrees centigrade

How much does the temperature of the ice rise in the first 30 seconds?

• 0 degrees centigrade

• 6 degrees centigrade

• 3 degrees centigrade

• 1 degree centigrade

What is the temperature of the ice at 90 seconds?

• 2 degrees centigrade

• -1 degree centigrade

• 0 degrees centigrade

• 1 degree centigrade

What type of curve is used to represent the temperature-time graph?

• Linear

• Parabolic

• Exponential

• S-shaped

Why is the horizontal axis placed high up on the graph paper?

• To fit the graph on the paper

• To accommodate positive temperature values

• To make the graph look symmetrical

• To accommodate negative temperature values

What happens to the temperature of the ice as it reaches the melting point?

• It continues to rise

• It decreases

• It fluctuates

• It remains constant

What conclusion can be drawn about the temperature of ice as it melts into liquid water?

• It fluctuates

• It rises continuously

• It remains constant at 0 degrees centigrade

• It decreases

What is the significance of the constant temperature observed during the melting of ice?

• It suggests an error in the experiment

• It represents the melting point of ice

• It shows the ice is not melting

• It indicates a rapid phase change
