The standard temperature and pressure conditions enthalpy is usually measured under are 1kPa and 273K (option A).
<h3>What is enthalpy?</h3>
Enthalpy in thermodynamics is a measure of the heat content of a chemical or physical system.
Enthalpy is the sum of the internal energy and pressure times volume It can be calculated using the following formula:
H = E + P V
Where;
H = Enthalpy
E = internal energy
P = pressure
V = volume
However, the enthalpy of a substance is usually measured under standard temperature and pressure.
- The standard temperature is 273 Kelvin or K
- The standard pressure is 1kPa

Answer:
21.1cm or 10.1cm
Explanation:
Since the percent error is 35.5% and the experimental measurement was 15.6cm, the two possible values for the actual measurement are 15.6 plus 35.5% of 15.6 or 15.6 minus 35.5% of 15.6.
This is this:
15.6 + (0.355 x 15.6)
= 15.6 + 5.54
= 21.1cm
Or this:
15.6 - (0.355 x 15.6)
= 15.6 - 5.54
= 10.1cm
