Answer:Reliability
Explanation:
Reliability of a test refers to how consistently a test measures a characteristic under the same conditions.
Reliability can be defined as the degree of consistency of which a chemical test gives a similar result. measure. A test is said to be highly reliable when it gives the same repeated result under the same conditions of measure.
But when a test gives different results under the same condition of measure it has a low reliability.
Hence, If a test yields consistent results every time it is used, it has a high degree of reliability.
Answer:
Explanation:
What does it mean by are represented by is it like cells when things can a cell molecule?
A decrease in temperature will cause a decrease in the volume of a sealed balloon filled with air. Temperature and pressure usually act together.This is because, reducing the temperature of a volume of gas will reduce the kinetic energy of the atoms of the gas, leading to a slower movement of the atoms and thus reducing the number of time the particles of the gas collide will the wall of the container; this means that the pressure has been reduced. This will reduce the volume of the gas. The reverse is also true.
The new pressure changed relative to the original by a factor of 8/3.
<h3>What is the change in the pressure?</h3>
Using the ideal gas equation;
PV = nRT
P = pressure
V = volume
n = number of moles
R = gas constant
T = temperature
P1 = nRT/V
P2 = 4n * R * 2T/3V
Hence;
P2/P1 = 4n * R * 2T/3V ÷ nRT/V
P2/P1 = 4n * R * 2T/3V * V/nRT
P2/P1 =4 * 2/3
= 8/3
