B. do the experiment more than once
Explanation:
To do a multiple trials of an experiment, it is best to do the experiment more than once.
Experimental trials are mere replication of the procedures in an experiment.
- Most hypothesis on which experiments are based must be repeatable.
- When experiments are repeated through several trials, their accuracy is increased.
- Multiple trials clearly makes it easy to make meaningful deductions from an experimental process.

Answer: Temperature final = 103 °C
Explanation: To solve for final temperature we use the equation of heat:
Q= mc∆T
Next derive the equation to find final temperature
Q = mc(T final - T initial)
Q / mc = T final - T initial
Transpose T initial and change the sign so that T final will be left.
T final = Q / mc + T initial
Substitute the values:
T final = 305 J / 28.8 g x 0.128 J/(g°C)
= 305 J / 3.6864 J/°C
= 82.7 + 20.0°C
= 103 °C final temperature.
