Are compact fluorescent bulbs cool to the touch?
Compact fluorescent bulbs do produce some heat, but they are cooler to the touch compared to incandescent bulbs. The heat produced is minimal and generally not enough to cause burns or discomfort upon contact. It is recommended to allow the bulb to cool down before handling it, especially if it has been on for an extended period of time.
What kind of light bulb gives off the most heat?
Incandescent light bulbs give off the most heat compared to other types of light bulbs because they produce light as a byproduct of heat. This is due to the way they function by passing an electric current through a filament, which heats up and emits light.
Which sources of visible light can be cool to the touch?
Any efficient one can. The inefficient ones are those that turn most of their fuel or electricity into heat, and only a small part of it into light. A few efficient light sources are: -- CFL bulbs -- fluorescent minerals -- fluorescent light tubes -- the hind end of fireflies
Do incandescent bulbs give off a lot of heat?
This is a trick question because the person asking it expects you to not know much. He or she is expecting you to say 'yes, because its too hot to touch'. But really, there are many many things that need to be considered when you say 'a lot of heat'. If you are comparing incandesent bulbs with florescent bulbs that give off the same amount of light measured in lumens, at say 20 degrees celcius, then answer is that the incandescent bulb gives off more heat. But if you vary the size of the bulb, the shape of the bulb, the location of the bulb, the environment of the bulb, the wattage of the bulb, or many other things, you can have an incandescent bulb that does not 'give off a lot of heat'.
Do incandescent and fluorescent bulbs produce the same amount of heat?
No, incandescent bulbs produce more heat than fluorescent bulbs. Incandescent bulbs generate light by heating a filament, which also emits heat. Fluorescent bulbs produce less heat because they use electricity to excite gas inside the bulb, which then emits light.

The heat produced is minimal and generally not enough to cause burns or discomfort upon contact.

Why is fluorescent lighting better for an aquarium than incandescent lighting?
An aquarium is sensitive to temperature changes. Incandescent lighting gives off much more heat than fluorescent lighting.
Which type of energy other than light energy is produced by incanduscent lights?
Incandescent lights produce heat energy in addition to light energy. This heat energy is a byproduct of the light-producing process and is why incandescent lights can become hot to the touch when operating.

What direction of heat flow when a warm object and a cool object touch?
The heat will transfer to the cooler object.
Is a LED light incandescent?
No, incandescent lights give off heat. LED do not.
What is the direction of heat flow when a warm object and cool object touch?
from warm to cool, warmth is energy, coolness is the absence of energy.

What is a chemical reaction that's absorbs energy called?
An Endothermic reaction. If you touch the reaction vessel it will feel cool/cold, as it is taking in heat energy. By contract an Exothermic reaction is one that gives out heat. If you touch the reaction vessel it will feel warm/hot as it is liberating heat energy.
How much heat does an incandescent bulb produce when it is turned on?
An incandescent bulb produces heat when turned on, with about 90 of its energy being emitted as heat and only 10 as light.
Why the stone countertop in the lab feels cool when you place your hand on it?
The stone countertop feels cool to the touch because it has a high thermal conductivity, which means it can absorb and dissipate heat quickly. When you touch the countertop, it draws heat from your hand, making it feel cold.
