What is the chemical symbol for gold?
Answer: Au. The chemical symbol for gold is Au, from the Latin 'aurum'. Silver (Ag) comes from 'argentum'. Chemical symbols are often derived from the Latin names of the elements.
What is the boiling point of pure water at sea level?
Answer: 100 °C. Pure water boils at 100 degrees Celsius (212 degrees Fahrenheit) at sea level, under normal atmospheric pressure of 1013 hPa. The boiling point drops as altitude increases.
Which subatomic particle carries a negative electric charge?
Answer: The electron. The electron carries a negative electric charge. The proton carries a positive charge and the neutron is electrically neutral. The positron is the antiparticle of the electron, with a positive charge.
Which force keeps the planets in orbit around the Sun?
Answer: The gravitational force. The gravitational force, described by Newton and then by Einstein, is the force that keeps the planets in orbit around the Sun. It depends on the mass of the objects and the distance between them.
Which phenomenon explains why stars seem to twinkle at night?
Answer: Turbulence in Earth's atmosphere. The twinkling of stars is caused by turbulence in Earth's atmosphere. Layers of air at different temperatures bend the light from the stars in a random way, creating this flickering effect.
