Why does pouring hot water over a tight jar lid will loosen it? Hot water makes the metal of the jar expand; this makes the cover loose. Most objects expand when heated because they are made of molecules that ar
But this process does not always happen easily as the plates are stiff, rough, and under a lot of pressure from surrounding plates. The tectonic plates tend to pull at or push on each other on either side of a fault for long periods of time without moving much at all, wh...
In other words, when you heat an object, that object expands and becomes larger due to the change in the object's temperature. Raising an object’s temperature, in this case, the metal lid, causes it’s molecules to move faster. The faster molecules move, the more space they occupy. ...

Liquids expand when heated because of a phenomenon called thermal expansion. As heat energy increases in a substance, the molecules move faster and... Learn more about this topic: Thermal Expansion | Coefficient, Equation & Examples from
How does heat affect the movement of molecules? How does temperature affect the direction of heat movement? Why do surface currents move a lot of heat? Why does temperature difference increase the rate of heat transfer? Why can an energy system contain a certain amount of heat? Why does ...
Every molecule making up every cell's membrane contains phosphorous (the membrane molecules are called phospholipids), and so does every molecule of ATP (the main energy source of all cells). Potassium makes up 1 percent to 2 percent of the weight of any plant and, as an ion in cells, ...
When we heat up water, it lets the hydrogen bonds between molecules stretch. As a result, the bonds within the water molecule can contract a bit. When they contract, they can release the energy they had while stretched. Losing energy is basically cooling down a far as thermodynamics is conc...
Considering a move from Shopify to WooCommerce? You’re in the right place. Whether you’re looking for more flexibility, custom checkout options, or simply the ability to pay only for what you need — and never for what you don’t — WooCommerce has the options to make it happen. ...
Non-ionizing radiation has enough energy to move atoms in a molecule around or cause them to vibrate, which can lead to heat but it can’t damage DNA directly.” How much RF energy you are exposed to depends on how your smart meter sends its signals, and how far from its antenna you...
