Questions and Answers

Why did Martin use a container made of wood in the experiment?

To prevent heat loss to the surroundings (correct)

To speed up the experiment

To make the water boil faster

To observe the reaction of wood with water

Why was it necessary for the experiment to be conducted over a short period of time?

To reduce errors caused by external factors affecting the air temperature (correct)

To match the duration of other experiments conducted simultaneously

To allow time for the wood to absorb water

To show a longer time lapse in the experiment

What is the relationship between the temperature of the air and distance Y based on Martin's results?

Temperature increases as distance Y decreases

Temperature decreases as distance Y increases (correct)

Temperature remains constant regardless of distance Y

Temperature increases as distance Y increases
