Laboratory Questions Circle the questions that have been assigned. Part A.1. The 200-mm test tube also contained some water (besides the metal) that was subsequent y acalormeter ta calorimeter (in Part A.4). Considering a higher specific heat for water, will the temperature change be higher, lower, or unaffected by this technique error? Explain. g the specific heat of a metal, Josh used the highest measured temperature for calculating the n the extrapolated temperature. Will this decision result in a higher or lower specific 2 Part A.5. In measurin metal's specific heat rather the heat value for the metal? Explain.

Explanation / Answer

1) q = m * c * T

Where

m = mass

c = Specific Heat

T = temperature change

q = Heat absorbed or released

T = q/ m*c

The temperature change is directly proportional to amount of heat and inversely proportional to

Specific heat and mass

Besides the metal some water was subsequently added to the calorimeter, that means, mass is    increased.

If mass is increased, temperature of the water will decrease more.

Due to this technique error, the temperature change in the calorimeter will be lower.

2) In measuring the specific heat of a metal, Josh used the highest measured temperature for calculating the metal’s specific heat rather than the extrapolated temperature. This decision result in a lower specific heat value for the metal.

Explanation:

q = m c t

t = t final – t initial

The extrapolated temperature is used to determine the maximum temperature of the mixture rather than the highest recorded temperature in the experiment; his decision will result in a lower specific heat value for the metal, because the temperature change is inversely proportional to Specific heat
