Worked Solution & Example Answer:A student carried out an experiment to measure the specific latent heat of fusion of ice - Leaving Cert Physics - Question 2 - 2013
Step 1
Draw a labelled diagram of the apparatus used in the experiment.
Answer
To draw the labelled diagram, include the following components: a calorimeter (to contain the warm water), a thermometer (to measure the temperature), and ensure all connections are visually represented. Show the ice being added to the calorimeter and provide labels for each part of the apparatus, ensuring clarity in its function.
Step 2
How did the student prepare the ice for the experiment?
Answer
The student prepared the ice by ensuring it was placed into the freezer for sufficient time to ensure it was fully frozen before the experiment began. This preparation ensures that the ice is at the correct temperature when added to the warm water.
Step 3
Step 4
Step 5
Why did the student use warm water in the experiment?
Answer
The student used warm water to ensure that heat could be transferred to the ice more effectively, allowing it to melt completely and facilitating the measurement of the temperature change, which is crucial for calculating the latent heat.
Step 6
What precaution did the student take when adding the ice to the water?
Answer
The student ensured that the ice was added gradually to prevent a sudden temperature drop in the water. Additionally, safety measures such as using gloves were adhered to in handling the ice to prevent frostbite.
