Fill in the blank: A thermometer that uses a liquid expanding in a glass tube to measure temperature is known as a ___. | Card: 5 / 50 |
![]() False, mercury thermometers are used in clinics but not in schools due to safety concerns. | Card: 8 / 50 |
What type of thermometer is colored red or blue and typically used in laboratories? | Card: 15 / 50 |
Bimetallic thermometers use metal expansion.
| Card: 20 / 50 |
What is the primary advantage of thermoelectric thermometers over traditional bulb thermometers? | Card: 21 / 50 |
Thermoelectric thermometers are faster, more cost-effective, and easier to read compared to traditional bulb thermometers. | Card: 22 / 50 |
Fill in the blank: A thermocouple consists of two different conductors joined at one end, where the temperature difference creates a ___ that is converted to a temperature reading. | Card: 23 / 50 |

A bimetallic thermometer bends due to unequal expansion of the two metal strips, which moves a pointer on a dial to indicate temperature. | Card: 28 / 50 |
Fill in the blank: Temperature strips use ___ to show temperature changes through color variations. | Card: 29 / 50 |
What is the relationship between the Kelvin and Celsius scales at the freezing point of water? | Card: 33 / 50 |
![]() To convert Celsius to Kelvin, use the formula T = t + 273. Therefore, 100 °C = 100 + 273 = 373 K. | Card: 36 / 50 |
Heat is defined as energy in transfer, moving from an object at a higher temperature to one at a lower temperature. | Card: 40 / 50 |
Convection involves the movement of hotter, less dense fluid rising through cooler, denser fluid, creating convection currents that transfer heat. | Card: 44 / 50 |
True or False: Radiation requires direct contact between objects to transfer heat. | Card: 45 / 50 |
False. Radiation transfers heat via electromagnetic waves and does not require contact between objects. | Card: 46 / 50 |
Riddle: I can warm you up without touching you; I travel through space with waves, what am I? | Card: 47 / 50 |
