Question 3/Multiple Choice Worth 2 points) (03.04 MC) The words thermometer hypothermia, and thermodynamics share a common root word. Based on that root word, what do all three have in common? Cold Heat Weather Writing

## Step 1<br />The problem asks us to identify the commonality among the words thermometer, hypothermia, and thermodynamics based on their shared root word. The root word in question is "thermo-".<br /><br />## Step 2<br />The root word "thermo-" is derived from the Greek word "thermos", which means "heat". This root word is used in all three words: thermometer, hypothermia, and thermodynamics.<br /><br />## Step 3<br />A thermometer is a device used to measure temperature, which is a measure of heat. Hypothermia is a medical condition where the body loses heat faster than it can produce heat, leading to a dangerously low body temperature. Thermodynamics is a branch of physics that deals with heat and temperature and their relation to energy and work.<br /><br />## Step 4<br />Given these definitions, it is clear that all three words are related to heat. Therefore, the correct answer is "Heat".
