Answer:
Sand has less specific heat than water.
Explanation:
Specific Heat is amount of heat needed per unit mass, to raise temperature by 1 degree celsius.
More specific heat means more heat energy needed to increase temperature. It implies - more time needed to absorb heat, increase temperature; and also more time needed to lose its heat.
Less specific heat means less heat energy needed to increase temperature. It implies - less time needed to absorb heat, increase temperature; and also less time needed to lose its heat.
Sand has less specific heat than water. So, it needs less heat absorption to increase temperature by per unit (celsius) ; than water. Hence, same level of heat to both sand & water ; increase temperature of sand more than water, & make it more hot.

Answer:
In an experiment the independent variable is special type of control which is control by the experimenter, and it effect the dependent variable.
Explanation:
In dependent variable:
The dependent variable is the variable which is controlled by the experimenter to check its effect on dependent variable.
Dependent variable:
It is variable which being measured in an experiment and which is directly depend upon independent variable.
The both variables are relate in term of cause and effect. The independent variable is changed by experimenter and its effect produce in dependent variable is then measure.
For example:
To measure how sleep of student effect the test score. The time for a sleep is given by experimenter it is independent variable which may exceed or decreased. It depend upon experimenter choice but the effect on score is dependent variable which depend upon the time of sleep.
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.
