2) a ________ is used to measure temperature.
3) ice is ____ dense than water
4) adding heat to a ________ increases the the motion of molecules
What are your choices for these blanks?
1) Science is the study of temperature.
To understand the concept of temperature, one should refer to the scientific discipline called "Thermodynamics." Thermodynamics is a branch of physics that deals with the relationships and behavior of heat and temperature. By studying thermodynamics, scientists gain knowledge about temperature, its measurement, and its effects on matter.
2) A thermometer is used to measure temperature.
A thermometer is a device used to measure temperature. It typically consists of a narrow tube containing a liquid (such as mercury or alcohol) that expands or contracts with changes in temperature. The temperature is determined by observing the level of the liquid in the tube or by using electronic sensors in modern digital thermometers.
3) Ice is less dense than water.
Water has a unique property where its density decreases as it freezes and turns into ice. As water approaches its freezing point and starts to form ice crystals, the molecules arrange themselves in a hexagonal lattice structure, which increases the space between the molecules. This structural change leads to a decrease in density. That's why ice floats on water instead of sinking, as most solid substances would do.
4) Adding heat to a substance increases the motion of molecules.
When heat is added to a substance, it transfers thermal energy to the molecules within that substance. As a result, the molecules gain kinetic energy, which leads to an increase in their motion. This increase in motion can be seen as an increase in temperature or a change in the physical state of matter (e.g., from a solid to a liquid or from a liquid to a gas). The added heat energizes the molecules, causing them to vibrate, rotate, and move more quickly.
