Answer : The temperature of neon gas will be, 221.0 K
Explanation :
To calculate the temperature of neon gas we are using ideal gas equation.
where,
P = pressure of neon gas = 96.7 kPa = 0.955 atm
Conversion used : (1 atm = 101.3 kPa)
V = volume of neon gas = 9.50 L
T = temperature of neon gas = ?
R = gas constant = 0.0821 L.atm/mole.K
w = mass of neon gas = 10.00 g
M = molar mass of neon gas = 20 g/mole
Now put all the given values in the ideal gas equation, we get:
Therefore, the temperature of neon gas will be, 221.0 K
A change which would remove the source of this error is to: Test a fourth group, in which participants do not receive the mineral supplements.
<h3>What is a scientific method?</h3>
A scientific method can be defined as the various techniques that are adopted to observe, investigate, examine and study a particular thing while giving explanations on the basis of the evidence, theory, proof, hypothesis, or factual information they derived from the research work.
In this scenario, a claim was made by the company its mineral supplements can effectively prevent common cold. However, this claim was disputed by a scientist because there exist an error in the group setup.
<h3>How to remove an error in science</h3>
For this investigation, an effective and efficient way to remove this source of error would be by testing a fourth group, in which the mineral supplements is not administered to any of the participants.

Answer:
The answer to your question is Power = 0.98 W or 9.8 x 10⁻⁴ kW
Explanation:
Data
Power = ?
mass = 100 g = 0.1 kg
distance = 1 m
gravity = 9.8 m/s²
Formula
Power = Work / time
Process
1.- Calculate the Work
Work = Force x distance
Force = mass x gravity
Work = mass x gravity x distance
Work = (0.1 kg)(9,8)(1)
Work = 0.98 J
2.- Calculate the power
Power = 0.98 J / 1 h
Power = 0.98 W or 9.8 x 10⁻⁴ kW
