What else can I help you with?
Do cooled substances expand?
No, cooled substances typically contract or shrink in volume due to a decrease in temperature causing the particles to move more slowly and come closer together. This is known as thermal contraction.
What happens as most substances are cooled?
Sometimes they get cold or start to freeze.
Do metals expand when they are cooled?
No, most substances contract with cooling, only some exotic substances (eg water) expands when cooled.
Why is the U-tube cooled?
The U-tube is cooled to maintain a steady temperature level inside the tube. By cooling the U-tube, any fluctuations in temperature can be minimized, ensuring more accurate measurements and observations of the substances flowing through it.
Why does a balloon shrink when cooled?
because the particles of the compound, called atoms, vibrate more when heated and then when cooled the
What is a transparent fusion product of inorganic substances that have colled to a rigid state without crystallizing?
Glass is a transparent fusion product of inorganic substances that have cooled to a rigid state without crystallizing.
What are the different types of condenser and how do they differ in terms of functionality and efficiency?
There are two main types of condensers: air-cooled and water-cooled. Air-cooled condensers use air to remove heat from the refrigerant, while water-cooled condensers use water. Air-cooled condensers are typically less efficient but easier to install, while water-cooled condensers are more efficient but require more maintenance and space. Overall, water-cooled condensers are more energy-efficient and better suited for larger cooling systems.
When a substance is cooled down it usually expands true or false?
False. Most substances contract or shrink when they are cooled down because cooling reduces the kinetic energy of the particles in the substance, causing them to move closer together.
Is a liquid cooled internal combustion engine more effecient than an air cooled engine?
Not necessarily but usually
Which of the two metals contract more when cooled?
Generally, all metals contract when cooled. However, the rate at which they contract depends on their coefficient of thermal expansion. In general, materials with higher coefficients of thermal expansion will contract more when cooled.
What are two or more substances that are together but not combined?
two or more subsantes (a mixture of substances) !
What are the advantages and disadvantages of an air cooled condensers over that of a fan cooled in refrigeration?
The air cooled can be more efficient because they will use less energy. They are difficult to maintain if it stays too hot.
