八年级物理《物态变化》练习题（Eight grade physics change of state exercises）

八年级物理《物态变化》练习题（Eight grade physics change of state exercises） Eight grade physics change of state exercises (1) temperature and thermometer; 1, the concept of temperature. Temperature refers to objects. The instrument for measuring temperature is. 2, cold winter, hand to touch the iron and wood on the outside, feel more cold iron. The following answer is correct A, because of low temperature, B ratio of iron wood because of iron wood heat transfer faster C, this is just human delusion, D, the above answer is incorrect 3 Celsius temperature. Celsius temperature regulation: 1 standard pressure, the temperature of the ice water mixture is, the temperature of boiling water is, and the temperature between them is equally divided into equal parts. The symbol for centigrade temperature is... 4, use the thermometer before you see its range, and then see its graduation value. It is necessary to see clearly that the range is to prevent the thermometer from being used at the time of use and that the thermometer is too small to measure the range. Look at the graduation mark so that you can read quickly while reading. 5, the use of temperature time, (1) its glass bubble should be immersed in the object (such as liquid), do not touch the container, or. (2) you cant read until the thermometer is steady. (3) the thermometer shall remain in the object to be measured while reading. (4) when reading, the eyes should be in line with the sight. 6 thermometer. Thermometer temperature range is. The role of a glass tube in a thermometer is. The thermometer is often forced to drop several times before use. 7. (05 years Guangdong, Shantou) measure the temperature in a beaker with a thermometer. The correct way is in several of the methods shown in Figure 7 8, the thermometer shows the number is ________. C Chinese Antarctic expedition team successfully reached the highest point of the Antarctic ice dome, the gas temperature of minus 80 degrees Celsius, with the thermometer _______ _ (optiona
