Answer:
See below
Step-by-step explanation:
heat gained by metal + heat lost by water = 0
m₁C₁ΔT₁ + m₂C₂ΔT₂ = 0
C₁ = -(m₂C₂ΔT₂)/(m₁ΔT₁)
The factors determining C₁ are
- mass of water
- temperature change of water (T_f - Ti)
- mass of metal
- temperature change of metal (T_f - Ti)
Any factor that makes the numerator higher or the denominator lower than what you thought, will give a calculated C₁ that is too high (and vice versa).
The major sources of uncertainty are probably in determining the temperatures, especially the initial and final temperatures of the metal. However, you will have to decide what the principal factors were in your experiment.
For example, did the metal have a chance to cool during the transfer to the calorimeter? How easy was it to determine the equilibrium temperature, etc?
Factors Affecting the Calculation of Specific Heat Capacity

Ti lower Ti higher
T_f higher T_f lower
Metal Metal

Ti higher Ti lower
Answer:
True
Explanation:
If you see distilled water, it's a pure substance. That means that there are only water molecules in the liquid. A mixture would be a glass of water with other things dissolved inside, like one of those powders you take if you get sick or Kool-Aid.
Answer:
Strong acid breaks up into ions
Explanation:
The sign's glass absorbed 25466.7 J
<h3>
Further explanation</h3>
Given
The temperature of glass : 23.5 °C to 65.5 °C
mass = 905 g
the specific heat capacity = 0.67 J/g °C
Required
Heat absorbed
Solution
Heat absorbed by sign's glass can be formulated :
ΔT=65.5 - 23.5 = 42
Answer:
The answer to your question is the letter C. three times as much
Explanation:
Data
First step = 6 m
Second step = 18 m
Potential energy is the energy stored that depends on its position.
Formula
Pe = mgh
m = mass; g = gravity; h = height
Potential energy of the first step
Pe1 = 6mg
Potential energy of the second step
Pe2 = 18mg
-Divide the Pe2 by the Pe1
Pe2/Pe1 = 18mg/6mg
= 3
