Answer:
i don't know
Explanation:
I really don't get dis and i need help thanks peeps
Maybe not all of it because the heat would go back in forth in the aluminum bar and some of it will be given and some may even be lost because heat is just atoms moving faster and eventually those atoms will slow down
<span>The answer should be false, because mass should not have to do with how bright a star is

Rub the magnet on the iron an it will cause a stronger force of attraction. Hope this helped!
Since there is no phase change, we can use the heat equation,
Q = mcΔT
where Q is the amount of energy transferred (J), m is the mass of the substance (kg), c is the specific heat (J kg⁻¹ °C⁻¹) and ΔT is the temperature difference (°C).
Q = 2000 J
m = 100 g = 0.1 kg
c = ?
ΔT = (70 °C - 50 °C) = 20 °C
By applying the formula,
2000 J = 0.1 kg x c x 20 °C
c = 2000 J / (0.1 kg x 20 °C)
c = 1000 J kg⁻¹ °C⁻¹
Hence, the specific heat capacity of the liquid is 1000 J kg⁻¹ °C⁻¹.
