Mass is always conserved in a physical change. Energy may be released or absorbed when a substance changes from one physical state to another. In a chemical change, a chemical reaction yields a completely new substance. A substance's particles are changed during a chemical reaction.

if the same amount of heat is added to 50.0 g samples of each of the metals, which are all at the same temperature, which metal
Salsk061 [2.6K]

The metal which will reach the highest temperature is the metal with the lowest specific heat capacity.

<h3>What is the amount of heat added to each metal?</h3>

The amount of heat Q = mcΔT where

  • m = mass of metal
  • c = specific heat capacity of mateal and
  • ΔT = temperature change

<h3>Temperature change of the metal</h3>

Making ΔT subject of the formula, we have

ΔT = Q/mc

Given that Q and m are the same for each metal,

ΔT ∝ 1/c

We see that the temperature change is inversely proportional to the specific heat capacity.

Since the metals are at the same temperature, the metal which will reach the highest temperature is the metal with the lowest specific heat capacity.

So, the metal which will reach the highest temperature is the metal with the lowest specific heat capacity.

109/8.56=12.7
50+12.7
V=62.7

Mass= Volume x Density so i divided the mass and density to get the volume. and afterwards i would just add it to the mass to get my final answer
