Given that:
Mass (m) = 20 g = 0.02 Kg,
temperature (T₁) = -10°C = -10+273 = 263 K
temperature (T₂) = 10°C = 10+273 = 283 K
Specific heat of water (Cp) = 4.187 KJ/Kg k
We know that Heat transfer (Q) = m. Cp.( T₂ - T₁)
= 0.02 × 4.187 × (283-263)
<em> Q = 1.67 KJ</em>
<em>Heat transferred is 1.67 KJ</em>

Answer:
The answer is D.
Explanation:
When bases react with water, it will form OH- ions in the solution.
The equation for work is W=DxF
W being work
D being distance
F being force
That would make the equation
8x.5=4
Answer:
<em>During the new moon phase, the moon is not visible because Sometimes it can be detected by noting the visible absence of the stars that it blocks. Additionally, during the new moon, sometimes enough light is reflected off the surface of the Earth that the disk of the moon is faintly visible</em>
