What is the coldest liquid on Earth? Liquid helium Is liquid nitrogen or liquid oxygen colder? Liquid nitrogen has a lower boiling point at −196 °C (77 K) than oxygen’s −183 °C (90 K), and vessels containing liquid nitrogen can condense oxygen from air: when most of the nitrogen has evaporated from such a vessel, […]
What causes high estrogen in men?
What causes high estrogen in men? With age, lifestyle, and other factors our body naturally increases the amount of aromatase enzyme which leads to the high amount of unwanted estrogen hormone in the body.

What are the two most important properties of stars?
What are the two most important properties of stars? A star can be defined by five basic characteristics: brightness, color, surface temperature, size and mass. Brightness. Two characteristics define brightness: luminosity and magnitude. Color. A star’s color depends on its surface temperature. Surface Temperature. Size. Mass. What is the most important characteristic of a star […]
What type of weather system brings calm clear weather?
What type of weather system brings calm clear weather? Most high pressure systems are large and move slowly. A high pressure system generally brings clear skies and calm air or gentle breezes. Air moves upward which lowers air pressure and causes the air to move faster. Rising air produces stormy weather. What type of weather […]
What will be the angle of reflection when angle of incidence is 60?
What are Carbohydrates give example?
What are Carbohydrates give example? Following are the important examples of carbohydrates: Glucose. Galactose. Maltose. Fructose. Sucrose. Lactose. Starch. Cellulose. What is the basic structure and function of a carbohydrate? Carbohydrates are the most abundant biomolecule on Earth. Living organisms use carbohydrates as accessible energy to fuel cellular reactions and for structural support inside cell […]
Which are not fundamental units?
Which are not fundamental units? The S.I unit of mass is kilogram (kg), while the S.I unit for acceleration is m/s2. Therefore the S.I unit of force is kg⋅m/s2. Since it is expressed as a combination of the units of mass, length, and time therefore it does not have a fundamental unit. Is Litre is […]
Why does the ray of light passing through the optical Centre of a lens not get any deviation?
Why does the ray of light passing through the optical Centre of a lens not get any deviation? The ray passing through optical center does no deviate because the curvature of the Lens at the incident and exit point are exactly opposite so the deviation at the first point is cancelled at the other point. […]
