Yasir wants to determine if there is a relationship between room color and sleep. Based on his research, Yasir makes an educated
Fynjy0 [20]

Yasir wanted to study the relationship between sleep and room color. So he has done all the background study required on the topic and arrived at a hypothesis that people fall asleep more rapidly in a room painted in blue color than in a room painted yellow. Yasir inquired several people which color they like better -yellow or blue- and used their feedback to decide whether his hypothesis was correct. There was no experiment conducted to observe the effect of a room color on sleep and the variables to be tested in the experiment were not properly identified.

Therefore, the correct answer would be,

An experiment that directly tests the hypothesis

Variables to be tested by an experiment

A 30.g sample of Al(s) is heated to 50°C and placed in a calorimeter containing 150g of water at 20°C. As the system approaches
SpyIntel [72]

Energy is transferred from the Al (solid) to water and the temperature of the water increases while the temperature of the Al (solid) decreases.

<h3>Heat energy</h3>

Heat energy is a form of energy transferred from one body to another due to a temperature difference between the bodies.

Heat energy is also known as thermal energy.

In heat transfer, heat is transferred from a body at higher temperature to a body at lower temperature.

In the heat transfer between the heated aluminium and the water, the solid aluminium is at a higher temperature than the water, hence, heat energy is transferred from the aluminium to water.

Therefore heat energy is transferred from the Al (solid) to water and the temperature of the water increases while the temperature of the Al (solid) decreases.
