Answer:
Energy absorbed by <u>Iron block</u> E (iron) = 460.5 J
Energy absorbed by <u>Copper block</u> E (Copper) = 376.8 J
Explanation:
To find the heat absorbed, we can use the formula as,
<em>q = m c ΔT</em>
Here, Mass = m = 10 g = 0.01 kg
ΔT = change in temperature = 400 - 300 = 100 K = 100 - 273 = -173 °C
c = specific heat capacity
c for iron = 460.5 J/kg K
c for copper = 376.8 J/kg K
Plugin the values in the above equation, we will get,
<em>q (iron) = 0.01 kg × 460.5 J/kg K × 100 K = 460.5 J</em>
<em>q (copper) = 0.01 kg × 376.8 J/kg K × 100 K = 376.8 J</em>
A material is a mixture if it is not pure
The answer is D because it sounds like the most ethical answer. The other choices are wrong because the could possibly hurt someone or an animal.
I showed maturity when I turn 13 year old
Answer:
What happens when it is squeezed is that its volume increases, the pressure of the material increases.
Explanation:
This is due to the fact that the elastic modulus of the sponge is high and withstands broad forces without deforming its structure, since the force is made within the proportional limit of its particles without modifying or permanently deforming them, that is why when stopping doing pressure or force on it its shape returns to being the original, this also happens due to the phenomenon of resilience
