I suppose that if there is air in the glass (small bubbles) the gas may expand more than the glass. The pressure inside the gas bubbles could conceivably cause cracks. I always thought it was just the uneven heating of the glass that caused certain parts to expand more rapidly than cooler parts, causing differential forces over the glass surface.APool555 said:My teacher was telling me how when you pour a hot liquid into a crystal glass that it will shatter. This is due to the transfer of heat, which speeds up the molecules in the cup. But air had something to do with it and I can not remember what. Does anyone have an idea? Thanks.
Thermodynamics is the branch of physics that deals with the relationship between heat and other forms of energy, such as work. It studies how energy is transferred between different systems and how it affects the properties of matter.
The first law of thermodynamics states that energy cannot be created or destroyed, only transferred or converted from one form to another. The second law states that in any energy transfer or conversion, some energy will be lost in the form of heat. The third law states that as temperature approaches absolute zero, the entropy (or disorder) of a pure crystal will approach zero.
Heat is the transfer of energy from a higher temperature object to a lower temperature object, while temperature is a measure of the average kinetic energy of the particles in a substance. In other words, temperature tells us how hot or cold something is, while heat tells us how much energy is being transferred.
Thermodynamics plays a crucial role in many everyday processes, such as cooking, refrigeration, and electricity generation. It also helps explain why things happen the way they do, such as why ice cubes melt in a warm room or why hot air rises.
Thermodynamics is essential in many engineering fields, including mechanical, chemical, and aerospace engineering. It is used to design and improve engines, power plants, refrigeration systems, and many other devices that involve the transfer or conversion of energy.
