How do we use science in our everyday life? Science informs public policy and personal decisions on energy, conservation, agriculture, health, transportation, communication, defense, economics, leisure, and exploration. It’s almost impossible to overstate how many aspects of modern life are impacted by scientific knowledge. What are 3 benefits of science? The advantages of Science and […]
What color is the photosphere as viewed from the ground on a clear cloudless day when the sun is highest overhead?
What color is the photosphere as viewed from the ground on a clear cloudless day when the sun is highest overhead? The photosphere appears bright yellow (almost white) as viewed from the ground on a clear, cloudless day. As the Sun approaches the horizon over an ocean, the photosphere appears orange-yellow and as the Sun […]
Is Absolute Zero Possible?
Is Absolute Zero Possible? Absolute zero, technically known as zero kelvins, equals −273.15 degrees Celsius, or -459.67 Fahrenheit, and marks the spot on the thermometer where a system reaches its lowest possible energy, or thermal motion. There’s a catch, though: absolute zero is impossible to reach. How do you explain thermodynamics to a child? Thermodynamics […]
What is the most important part of the electromagnetic spectrum?
What is the most important part of the electromagnetic spectrum? Infrared (IR) radiation – also referred to as thermal radiation – is the portion of the electromagnetic spectrum lying between visible light and microwaves. The most important natural source of infrared radiation is the sun. What is the order of increasing wavelength? The electromagnetic spectrum […]

What will the atmosphere be like in 2025?
What will the atmosphere be like in 2025? They found that by 2025, atmospheric carbon dioxide (CO2) levels will very likely be higher than they were during the warmest period of the last 3.3 million years. Dr. A striking result we’ve found is that the warmest part of the Pliocene had between 380 and 420 […]
What are 2 types of kinetic friction?
What are 2 types of kinetic friction? In general, the friction is of the following two types: (1) Static friction. It is the friction, experienced by a body, when at rest. (2) Dynamic friction. It is the friction, experienced by a body, when in motion. (a) Sliding friction. (b) Rolling friction. (c) Pivot friction. 14.7. […]

How many properties do ionic compounds have?
How many properties do ionic compounds have? Properties of Ionic Compounds Ionic Compounds have high boiling and melting points as they’re very strong and require a lot of energy to break. The electrostatic forces of attraction between oppositely charged ions lead to the formation of ions. Ionic compounds form crystals. Is sugar a covalent or […]
