If heat is applied to a confined fluid, the temperature of the fluid will increase, which will cause the fluid to expand. This can lead to an increase in pressure within the confined space, potentially causing the container to rupture if the pressure exceeds its limits.
For heat to be transferred by convection, it requires the movement of a fluid (liquid or gas) caused by temperature differences. As the fluid near a heat source becomes warmer, it becomes less dense and rises, displacing cooler fluid that then moves to take its place. This process creates a circulating flow of fluid that transfers heat throughout the medium.
When heat is removed from the fluid, the temperature of the fluid will decrease, causing the convection currents to slow down or even stop. This is because the temperature difference that drives the convection process will decrease, leading to a reduction in the movement of the fluid particles.
the liquid or gas must circulate to move the heat.
Heat transfer by convection occurs when a fluid or gas moves due to temperature differences, carrying heat with it. As the fluid or gas near a heat source becomes warmer, it expands and becomes less dense, causing it to rise and displace cooler, denser fluid. This movement transfers heat from the warmer area to the cooler area.
Convection currents occur in liquids when heat is applied to a fluid, causing it to expand and become less dense. This less dense, warmer fluid rises, while the cooler, denser fluid sinks, creating a circular movement. This process is driven by the transfer of heat energy within the liquid.
The density of a fluid goes down (becomes less dense) when heat is applied.
it melts
It would be convection. Convection occurs when heat is applied to a fluid.
Heat must have to be applied to the ice cube.
When heat is applied to powdered sulfur, it will melt and eventually vaporize. This process is called sublimation, where a solid substance bypasses the liquid phase and turns directly into a gas.

When heat is applied to fat, it begins to melt and liquefy due to the breakdown of its molecular structure. This process is known as melting, where the fat transitions from a solid to a liquid state. If the heat is increased further, the fat may eventually start to smoke and burn as it reaches its smoke point.
