The scientific questions that could be answered by this experiment are:

How does the particle size affect the rate of dissolution of the antacid?

What is the effect of changing the temperature on the rate of dissolution of the antacid?

Further Explanation:

A scientific question must be about the relationship of the dependent and independent variables in the investigation.

The independent variable is the variable that the experimenter manipulates and changes voluntarily. The dependent variable is the responding variable. It changes only in response to the manipulation that was done to the independent variable. The dependent variable is usually what is observed or measured in the experiment.

In the given investigation, the independent variables were temperature and/or particle size. For the experiment to be fair, all variables must be kept constant except the independent variable. To avoid confusion, only one independent variable is manipulated at a time. Therefore, in this experiment, either the temperature will be changed first, or the particle size. It would be confusing to change both at the same time.

The effect of the independent variables on the reaction will be observed, hence, it is the dependent variable. To narrow down which aspect of the reaction will be observed, the focus could be on the rate of dissolution or how fast the antacid dissolves.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.

Turtle hatchling survivorship rate is low in many turtle species due to predation. amanda researched the predatory rate on a species of turtle eggs in the red river. the eggs were harvested from trapped turtles and the egg's cloaca film (reproductive discharge) was either washed off or left on once gathered. research suggests that predators use the female's cloaca scent to locate the eggs. the eggs were only handled when wearing gloves and then reburied along islands where the turtles were trapped. the nests were monitored by cameras and manually on foot and data on nest predation were recorded. a. based on the experimental design, what is the dependent variable? b. based on the experimental design, what is the independent variable? c. based on the experimental design, what is the control?
