whats an dependent variable?

The effect/What you measure. also on the Y-axis

whats the control group?

The control is the group that serves as a standard of comparison.

whats an control variable?

Variables kept the same so they don’t affect results

How are a theory and an inference different?

A hypothesis is the prediction about the outcome of an experiment. An inference is conclusion drawn based on observations and prior knowledge

whats this property of water?

High specific heat

whats Universal solvent?

capable of dissolving more substances than any other liquid

whats Cohesion?

attraction between molecules of same substance

whats adhesion?

attraction between molecules of different substances

whats an example of cohesion?

H₂O molecules stick together ( droplets )

whats an example of adhesion?

H₂O sticks to other objects

what is high specific heat defined by?

the amount of heat needed to raise the temperature of 1 gram of a substance 1 degree Celsius

Why does water have a high specific heat?

because it takes more energy to increase the temperature of water compared to other substances
