Why is the variable that should stay constant “ the amount of time each beaker was left in different temperatures” and not the temperature of the room in which beakers were stored

The variable that should stay constant is the amount of time each beaker was left in different temperatures because we want to investigate the effect of temperature on the contents of the beakers over a fixed period of time. By keeping the time constant, we can isolate the impact of temperature alone on the substances in the beakers.

If the temperature of the room in which the beakers were stored was not constant, it would introduce an additional variable that could potentially influence the results. Temperature fluctuations in the room could affect the temperature of the beakers and lead to inconsistent or confounding results. By controlling and keeping the time constant, we can accurately assess the impact of temperature on the substances being studied without interference from external factors like room temperature fluctuations.
