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 g⁻¹ °C⁻¹) and ΔT is the temperature difference (°C).
Q = 322 J
m = 100.0 g
c = ?
ΔT = (50 - 25)
°C = 25 °C
By applying the formula,
322 J = 100.0 g x c x 25 °C
c = 322 J / (100.0 g x 25 °C)
c = 0.1288 J g⁻¹ °C⁻¹
Hence, the specific heat of gold is 0.1288 J g⁻¹ °C⁻¹.
Answer:
i edited it so you will have to read the numbers on the pics
Explanation:
Answer:
The Sun's temperature, which reaches around 15 million degrees Celsius in its core, steadily decreases with distance from the core, falling to 6000°C at its 'surface'. ... Instead, it rises to about 10,000°C in the chromosphere, and exceeds a million degrees Celsius in the corona.
Explanation:
Molar mass SiO2 = 28 + 32 = 60
<span>so moles sand = 3.4 x 10-7 / 60</span>
Answer:
3 atoms
Explanation:
it contains 2 atoms of hydrogen(H) and 1 atom of oxygen(O). So in total there are 3 atoms.
