Is a portable generator AC or DC?
Is a portable generator AC or DC? While the technique of producing electricity is the same in both types, AC and DC power become different in terms of their applications – the way in which loads receive electric power. For instance, generators for home use deliver AC power whereas cars use generator engines that produce […]
Why do balloons return to normal at room temperature?
Why do balloons return to normal at room temperature? When it is warmed up, the balloon regains its original volume and shape. Explanation 1: The volume of the balloon decreases by the low temperature, because the gas inside is cooled down. In a balloon, cooling the gas inside would cause the circumference to decrease. … […]
What is an example of ozone?
What is an example of ozone? An example of ozone is a gas used to purify water. An unstable, poisonous allotrope of oxygen having the chemical formula O3 . Ozone forms in the atmosphere through the process of photolysis, when ultraviolet radiation from the Sun strikes oxygen molecules (O2 ), causing them to split apart. […]
How do different isotopes affect the properties?
How do different isotopes affect the properties? 1 Answer. Different isotopes have different numbers of neutrons in their nuclei. Having a different number of neutrons does not affect either one of these properties, so isotopes of an element will behave (chemically) the same. However, the greater mass of a heavier isotope does provide some useful […]

How do smells affect the brain?
How do smells affect the brain? In our daily life, several fragrances appear and a sense of smell plays an important role in the physiological effects of mood, stress, and working capacity. Subsequently, the electrical signals are transmitted to the brain by olfactory sensory neurons via olfactory bulb and higher olfactory cortex [5,6]. What sense […]
Do humans emit energy?
Do humans emit energy? Yes, all objects, including human bodies, emit electromagnetic radiation. The wavelength of radiation emitted depends on the temperature of the objects. Such radiation is sometimes called thermal radiation. Most of the radiation emitted by human body is in the infrared region, mainly at the wavelength of 12 micron. Can Earth be […]
