To find out how hot or cold a body is, use a thermometer. A thermometer measures temperature by detecting changes in physical properties, like liquid expansion or electrical resistance, and displays the temperature on a scale.
Tiwari Academy Discussion Latest Questions
To measure temperature with a laboratory thermometer, immerse the bulb in the substance or environment being measured, wait until the liquid stabilizes, and then read the temperature from the scale. Ensure accurate placement.
Yes, when a thermometer is removed from water, the liquid column falls because it cools down and contracts. The liquid inside the thermometer shrinks as it loses heat, causing the column level to decrease.
Anna Mani was an Indian physicist and meteorologist known for her work on solar radiation and instrumentation. She made significant contributions to weather forecasting and was a pioneer in meteorological instrumentation in India.
Yes, some objects in the sky have temperatures exceeding the Sun’s core. For instance, neutron stars and supernova remnants can reach temperatures over 100 million degrees Celsius due to their extreme density and energy.
Here are the planets’ distances from the Sun (in AU) and average temperatures: Mercury (0.39 AU, 167°C), Venus (0.72 AU, 464°C), Earth (1.00 AU, 15°C), Mars (1.52 AU, -65°C), Jupiter (5.20 AU, -110°C), Saturn (9.58 AU, -140°C), Uranus (19.22 AU, ...
In India, Leh in Ladakh is among the coldest places, with temperatures dropping to -40°C. Phalodi in Rajasthan is one of the hottest, reaching up to 51.0°C. These extremes vary seasonally.
Animal body temperatures are measured using digital or mercury thermometers, typically rectally for accuracy. Each species has its own normal range: cats and dogs around 101-102°F, horses 99-101°F, camels 97-101°F, cows and buffaloes 100.5-102.5°F.
If someone says she has a fever of 101 degrees, she is most likely referring to the Fahrenheit scale. A temperature of 101°F is a common fever range, while 101°C would be dangerously high.
Each division of a laboratory thermometer with 50 divisions between 0°C and 100°C measures 2°C. This is calculated by dividing the total temperature range (100°C – 0°C) by the number of divisions.
