Explain how you could experimentally determine whether the outside temperature is higher or lower than 0 oC (32 oF) without using a thermometer.
Expert Solution & Answer
Interpretation Introduction
Interpretation:
The experimental method should be explained used to determine whether the outside temperature is higher or lower than 0oC without using a thermometer.
Concept introduction:
Change in temperature can lead to physical changes in the system. Such change indicates the temperature specifications.
Answer to Problem 1E
The change of the state of the water in both glasses is due to the movement of heat and causes physical transformation.
Explanation of Solution
Step 1: Take two glasses, glass A and B and fill them with freezing and normal water, respectively.
Step 2: Keep the glasses outside and notice the physical changes occurs. If the water in glass A (freezing water) starts melting and water in glass B (normal water) remains same, then the temperature is higher than 0°C.
In case the water in glass B (normal water) starts to freeze and water in glass A (freezing water) doesn’t show any change, then the temperature is less or equal to 0°C.
When the system comes in the contact of the outside environment or surroundings, the transfer of heat takes place. This transfer of heat causes physical changes in the system.
As in the experiment, the system are two water glasses and as soon these are subjected to outer environment some physical changes take place which indicates the temperature of the surroundings.
