Question

delta t means ______ in temperature.
a dilation
b change
heat energy is measured in what units?
a joules
b newtons
it takes a lot of energy to get the temperature of water to increase and eventually boil because water has a high ______ heat.
a specific
b target

Explanation:

• For the first question, in science, $\Delta T$ (Delta T) is a common notation for change in temperature. Dilation is related to expansion in a different context (like geometric dilation or dilation in materials due to heat in a more complex sense not directly what $\Delta T$ means).
• For the second question, heat energy is measured in Joules. Newtons are the unit of force.
• For the third question, water has a high specific heat. Specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius. Target heat is not a relevant scientific term in this context.

Answer:

1. B. change
2. A. Joules
3. A. specific
