The percent error of Chemistry student : 7.4%
<h3>
Further explanation
</h3>
Given
40 °C measurement
Required
The percent error
Solution
% Error : difference between the theoretical value and the actual value
or
% Error : Absolute Error / Accepted Value
Absolute Error = Measured Value - Accepted Value
% Error for Chemistry student :
1. Subtract the measurement value with the accepted value
= 40 °C - 43.2 °C
= -3.2 °C
2. Divide by the accepted value, and multiply by 100
= |-3.2/43.2| x 100%
= 7.4%
<span>The temperature change is greater when assuming that the mass is constant and the heat must be greater </span>in the result the heat of the metal as being reported too high.
hope it helps
Answer:
nuetrons
Explanation:
some helium atoms just a little thick and packing extra neutrons
At the top of the swing is your answer.
Kinetic energy increases as an object falls. Increase of speed also increases kinetic energy. The kinetic energy is at zero when an object is not moving
