Warmer atoms expand. There is also more movement. This is also explained when putting it into terms with solid vs. gas. In a solid, the atoms vibrate, but they can't move very far because there is not a lot of space between them. In a gas, on the other hand, the atoms are spread apart, and they move very fast. Putting it into context with water, the steam (gas) version is hot, and the ice cube (solid) version is cold. Which one moves more freely? The gas.
Answer:
The sun is heavier than all of the planets, thus having more gravity
Explanation:
Because the sun is heavier, it exerts more gravitational pull towards itself, thus keeping all of the planets in orbit.
The answer is B :) hope this helped at least
What is the specific heat of aluminum?
The specific heat of aluminum is 0.90J/g°C.
Given:
Heat absorbs = 677 J
Mass of the substance = 10 g
Initial temperature = 50°C
Final temperature = 125°C
Formula used:
Q = m x c x ΔT
which can also be written as,
Q = m x c x ( 
- 
)
where,
Q = heat absorbs
m = mass of a substance
c = heat capacity of aluminum
= Final temperature
= Initial temperature
Now, put all the values in the formula given above to get the specific heat of aluminum,
677g = (10g) x c x (125 - 50)°C
c = 0.9026 J/g°C
c = 0.90 J/g°C
