Answer:
The core turns its hydrogen to helium and stops nuclear fusion which causes the outer shells of hydrogen to collapse.
Explanation:
This results in higher temperature and pressure which in turn causes the outer shells to expand and cool as a red giant.
A) the prefix
For example with the prefix prop: 3 carbons
Propane: C3H8
Propene: C3H6
Propyne: C3H4
Answer:
Melting is a physical change with no change in temperature of the substance while when the object is set on fire, its temperature changes.
Explanation:
Melting cause physical change in any substance. The temperature of the substance remain same but the physical property changes i.e in melting substance changes its state from solid to liquid.
However, in case of setting a substance on fire the temperature changes along with the state of the substance.
Answer:
How to convert 45 gal to kg? You can use the following formula to convert from Gallon to Kilograms :
X(kg) = y(gal) / 0.264172053
To convert 45 Gallon to Kilograms:
X(oz) = 45(gal) / 0.264172053
Answer: 170.3435 kg
Thus when the heat is added in the system, temperature gets increases which in turn will increase the velocity of the molecule and these molecules will collide even faster . Thus kinetic energy within the molecule of an object increases when the heat is added to the system.
