Soal Suhu Dan Perubahannya

The correct answer is 77oF. This is because when converting from Celsius to Fahrenheit, you multiply the Celsius temperature by 9/5 and then add 32. In this case, 25 multiplied by 9/5 equals 45, and adding 32 gives us 77. Therefore, the temperature in Fahrenheit is 77oF.

The correct answer is kelvin. The Kelvin scale is the SI unit for temperature. It is based on absolute zero, the point at which all molecular motion ceases. Unlike the Celsius and Fahrenheit scales, which are based on the properties of water, the Kelvin scale starts at absolute zero and measures temperature in increments of kelvin.

When the bimetal is heated, the brass (kuningan) expands more than the iron (besi) due to its higher coefficient of linear expansion. This causes the bimetal to bend towards the iron side, as the brass tries to expand more than the iron can accommodate. Therefore, the correct answer is "membengkok ke arah besi" which means "bends towards the iron".

The reason for loosening the installation of PLN electricity cables is to prevent them from breaking during the night. This is because the cables tend to expand when they heat up, and if they are tightly installed, they may break or snap when they expand. By making the installation loose, the cables have room to expand without breaking, ensuring that the electricity supply remains uninterrupted during the night.

The correct answer is "suhu air yang mendidih". The fixed point on a Celsius thermometer is the temperature at which water boils, which is 100 degrees Celsius. This means that when the Celsius thermometer is placed in boiling water, it will show a reading of 100 degrees Celsius. Therefore, the fixed point on a Celsius thermometer is the boiling point of water.

Air tidak dipakai untuk mengisi termometer karena air membasahi dinding. Ketika air digunakan untuk mengisi termometer, air akan menempel pada dinding termometer dan tidak akan mengalir ke dalam tabung termometer dengan baik. Hal ini akan mengganggu akurasi pengukuran suhu yang dilakukan oleh termometer. Oleh karena itu, untuk menghindari kesalahan pengukuran, air tidak digunakan sebagai pengisi termometer.

The correct answer is "muschenbroek" because it is a tool used to investigate the expansion of various solid substances. A barometer is used to measure atmospheric pressure, a bimetal is used to measure temperature changes, and a thermometer is used to measure temperature. Therefore, muschenbroek is the most appropriate tool for investigating the expansion of solid substances.

Pemasangan jembatan besi bukanlah pemanfaatan pemuaian dalam kehidupan sehari-hari. Pemuaian adalah perubahan dimensi suatu benda akibat perubahan suhu. Namun, pemasangan jembatan besi tidak melibatkan perubahan suhu yang signifikan yang dapat menyebabkan pemuaian.

The correct answer is "tingkat panas suatu zat" because suhu suatu zat refers to the measure of the average kinetic energy of the particles in the substance. It indicates the level of heat or coldness of the substance.

Alkohol dapat mengukur suhu yang sangat tinggi karena memiliki titik didih yang tinggi. Hal ini memungkinkan alkohol untuk digunakan dalam pengukuran suhu yang melebihi batas suhu yang dapat diukur oleh air atau zat lainnya. Alkohol juga memiliki sifat yang tidak membasahi dinding tabung, sehingga memungkinkan pengukuran yang lebih akurat dan tidak terpengaruh oleh adanya cairan yang menempel pada dinding tabung.
