Question

Activity I: Use a thermometer (you may use a digital thermometer if available) to record the

temperature of pure ice placed in a beaker when melting, and carry out the same process to

measure the temperature of frozen salt water and record its melting point.

You are required to enter your observations in the table below:

Melting Point (

0 C) of Pure Ice Melting Point (

0 C) of Frozen Salt Water

Q2:

Activity II: Heat pure water in a beaker and record the temperature at which it boils. Then

carry out the same activity simultaneously with some salt added to the water and measure

the boiling point of salt water.

You are required to enter your observations in the table below:

Boiling Point (

0 C) of Pure Water Boiling Point (

0 C) of Salt Water

Q3: Compare your observations of both Activity I & II and deduce a conclusion for your

results.

Answer 1

Answer:

Activity I:

Melting Point of Pure Ice - ( 0°C)

Melting Point of Frozen Salt Water - ( 32°F or 0°C)

Activity II:

Boiling Point of Pure Water - (212 °F or 100°C).

Boiling Point of Salt Water - ( 100 °C or 212 °F)
