Question

use the data table to answer the question. what element in the table is constant? the mass is constant in this set of data. the change in temperature is constant in this set of data. the heat energy is constant in this set of data. there are no constant elements in this set of data.

Explanation:

Step1: Check each column

Check the values in the "Mass (g)", "$\Delta T$ ($^{\circ}$C)", and "Heat (q, J)" columns.

Step2: Analyze the "Mass (g)" column

The values in the "Mass (g)" column are \(30.00\), \(36.00\), \(42.00\), \(48.00\), \(54.00\). These values are not the same, so mass is not constant.

Step3: Analyze the "$\Delta T$ ($^{\circ}$C)" column

The values in the "$\Delta T$ ($^{\circ}$C)" column are \(14.00\), \(11.67\), \(10.00\), \(8.75\), \(7.78\). These values are not the same, so the change in temperature is not constant.

Step4: Analyze the "Heat (q, J)" column

The values in the "Heat (q, J)" column are all \(60.00\). So heat energy is constant.

Answer:

The HEAT ENERGY is constant in this set of data.
