Answer:
A. The same amount of heat is absorbed in both the experiments because the product of mass, specific heat capacity, and change in temperature are equal for both.
Explanation:
- The amount of heat absorbed by water (Q) can be calculated from the relation:
<em>Q = m.c.ΔT.</em>
where, Q is the amount of heat absorbed by water,
m is the mass of water,
c is the specific heat capacity of water (c = 4.186 J/g °C),
ΔT is the temperature difference (final T - initial T).
- <u><em>For trial 1:</em></u>
m = 30.0 g, c = 4.18 J/g °C, ΔT = 40.0 °C – 0.0 °C = 40.0 °C
<em>∴ Q = m.c.ΔT</em> = (30.0 g)(4.18 J/g °C)(40.0 °C) = <em>5023 J.</em>
- <u><em>For trial 2:</em></u>
m = 40.0 g, c = 4.18 J/g °C, ΔT = 40.0 °C – 10.0 °C = 30.0 °C
<em>∴ Q = m.c.ΔT</em> = (40.0 g)(4.18 J/g °C)(30.0 °C) = <em>5023 J.</em>
<em>A. The same amount of heat is absorbed in both the experiments because the product of mass, specific heat capacity, and change in temperature are equal for both. </em>

Hey there!
The answer would be A. When electrons. move easily through objects
In science, a conductor is a material that permits a flow of energy. A material that allows the flow of charged particles is an electrical conductor. A material that enables the transfer of thermal energy is a thermal conductor or heat conductor.
Hope this helps !
Answer:
Observe odor, determine pH, determine density, determine boiling point
Explanation:
The correct procedures that would be best to use to determine whether a beaker contains only distilled water would be to observe the odor of the liquid in the beaker, determine the pH of the liquid, determine the density, and then determine the boiling point of the liquid.
<em>Water is generally odorless and has a pH of approximately 7 with a density of 1 kg/m3 and a boiling point of 100 </em>
<em>. If the liquid in the beaker ticks all these conditions, then it can be established to be only distilled water.</em>
