a diagram showing how water is heated and cooled

Prompt 1: is a demonstration of a scientific experiment that shows the change in temperature of water over time. it starts with a thermometer in boiling water, and then water is added to the thermometer. the experiment is conducted in a beaker with a thermometer, and the temperature is observed to change. emphasizes the importance of accuracy in scientific experiments.

Prompt 2: presents a yti test demonstration, where two beakers are filled with two different solutions and two different liquids are mixed together. the test results show a color change, indicating a chemical reaction. also features two different types of chemical reactions, one in blue and the other in a grey box with a red background. provides instructions on how to perform the test and the expected results. additionally, there are two different chemical reactions in two separate boxes, showing the differences between them. emphasizes the importance of following the instructions carefully and ensuring that the reagents are of the same concentration for accurate test results.
