Answer 2

Answer:

There are many cases in which solid substance melts into liquid but temperature remain same.

Explanation:

An experiment to showing temperature remain same during phase change  is as follows:

• Take solid wax in a test tube and keep it in a hot bath.
• Measure the temperature of wax in test tube using a thermometer. at first the temperature will rise and reaches 50 degree celcius.
• Measure the temperature in every minute and the temperature will remain same that is 50 degree Celcius.
• At end, it shows that the temperature remains constant and the wax is also melted by absorbing heat.

Hence, it shows temperature remains constant while substance changes from solid to liquid.
