If a substance is not at its melting or boiling point, as the heat content of a sample of matter increases;
- Its temperature increases
- The space between particles increases
- The particles move faster
Explanation:
As heat energy is applied to a substance, its temperature increases. The molecules of the gain more kinetic energy and the bombardment between the molecules increase with frequency and energy. The distance between the molecules also increases and this is attributed to the expansion of substances when heated. This continues until temperatures are reached where the kinetic energy of the molecules is high enough to overcome the intermolecular forces between the molecules and the substance changes phase.

Answer:
increases only slightly; large
explanation
Water has one of the highest specific heats of any known liquid. This means that the temperature of a water sample _only increase slightly_______ with the input of a __large______ amount of energy.
Explanation:
equations to note:
density= mass/volume
mass= volume *density
volume= mass/density
you have a volume- 8.33cm3
you have a density- 2.07 g/cm3
Answer:
8.33cm3 * 2.07g/cm3= 17.24g
mass= 17.24g
The answer is: all true
<span>A. As the pressure of the gas increased, the volume of the gas decreased.
It is clear that if you compare the data on the left side. When the pressure increased the volume is decreased.
B. For all pairs of data of pressure and volume, P • V was appoximately the same.
The pressure is inversely related to the volume. You can take two data to prove it. Let use the first and second data
V * P= 1.03 * 50= 51.5
</span>V * P= <span>1.08 * 47.5= 51.3
C. For all pairs of data of pressure and volume, P • V mr001-1.jpg k for the same value k.
D. The regression equation was of the form V = kP–1 (which is the same as V = k/P).
The value of k can be expressed as k= P*V. If the equation is turned around, it could be expressed as V= k/P
The value of k is constant on different data, proved by the calculation on the second statement above. The value of k should be around 51.5
