Marshmallows expand in the microwave because the heat causes the air bubbles trapped inside them to expand, making the marshmallows puff up and increase in size.
The amount a bearing will expand when heated depends on factors such as material composition and temperature. However, typically a bearing will expand around 0.0005 inches per inch of diameter for every 100°F increase in temperature.
All balloons expand in heat.
yes, the heat makes the particles move and in the heat they expand.
To fit a bearing, first ensure that the housing and shaft are clean and free of debris. Heat the bearing in an oven or use a bearing heater to expand it slightly, then carefully slide it onto the shaft or into the housing. Use a press or a suitable tool to ensure it is seated properly without applying pressure to the rolling elements. Finally, allow the bearing to cool to room temperature, which will help it contract and fit securely in place.

When the temperature is colder the particles in the balloon travel slower, making the balloon not able to increase in size it decreases.When the temperature is hot it allows the balloon to expand because the particles in the balloon are moving rapidly. in conclusion the the cold makes the balloon decrease in size and the heat allows it to expand.
heat makes metal expand.
They expand.
The word 'compress' is the opposite of 'expand'.
Being made up of infra red rays which will move in all directions and refract when hitting paticles heat will always expand
heat does not necessarily expand.. the varying temperatures causes different elements that make up an object to expand or contract e.g. tar on the road expands in the heat and contracts in the cool and therefore cracks are formed in the road.
