What is the device that converts electrical energy to heat energy? Generator What are the three devices that change electricity to heat energy? (1) Heater and home appliances like press iron, geyser etc, converts electrical energy into heat energy. (2) Electric bulb and rods converts heat energy to light energy. (3) A motor and robot […]

What are characteristics of a high pressure system? A high pressure system has higher pressure at its center than the areas around it. Winds blow away from high pressure. Swirling in the opposite direction from a low pressure system, the winds of a high pressure system rotate clockwise north of the equator and counterclockwise south […]

Can binaural beats release dopamine? For instance, it might be that binaural beats induce, or increase the size of phasic dopamine bursts, which might have a stronger impact in individuals with a relatively low tonic dopamine level. What is the science behind binaural beats? Binaural beats are an auditory illusion caused by listening to two […]

Which of the following is the example of free convection? A microwave oven cooking a meal. Can heat be transferred by convection? When a fluid, such as air or a liquid, is heated and then travels away from the source, it carries the thermal energy along. This type of heat transfer is called convection. The […]

What are the causes of echo? Echoes. An echo is a sound that is repeated because the sound waves are reflected back. Sound waves can bounce off smooth, hard objects in the same way as a rubber ball bounces off the ground. Although the direction of the sound changes, the echo sounds the same as […]

What do electrical and thermal conductors have in common? Usually, electrical conductors have loosely bound electrons. Materials that conduct heat are thermal conductors. Metals typically conduct both heat and electricity. Carbon conducts ​electricity as graphite, but insulates as diamond, so the form or allotrope of a material can be important. What characteristics of metal make […]
