What are the four properties of an ionic compound? Properties Shared by Ionic Compounds They form crystals. They have high melting points and high boiling points. They have higher enthalpies of fusion and vaporization than molecular compounds. They’re hard and brittle. They conduct electricity when they are dissolved in water. They’re good insulators. Which of […]

What does hypothesis mean in simple terms?
What does hypothesis mean in simple terms? A hypothesis is a suggested solution for an unexplained occurrence that does not fit into current accepted scientific theory. The basic idea of a hypothesis is that there is no pre-determined outcome. What is the best definition for the word prediction? A prediction is what someone thinks will […]
How long does it take light to travel from the sun to Pluto?
What is the difference between solar time and solar day?
What is the difference between solar time and solar day? The sidereal day is measured with respect to the stars, while the solar day is the length of time measured from noon to noon. By noon, we mean the time when the Sun passes the celestial meridian, reaching its maximum height in the sky. How […]
What is the relationship between temperature and kinetic energy answers?
What is the relationship between temperature and kinetic energy answers? Kinetic energy is directly proportional to the temperature applied. Basically with increase in temperature the vibration / collision of molecules increase hence kinetic energy increases. What is the relationship between the kinetic energy of molecules in an object? Explanation: The kinetic energy of the molecules […]
Is gravity the same in a plane?
Is gravity the same in a plane? You are correct that the force of gravity is slightly less the further you get from the earth. Airlines typically cruise around 30,000 – 35,000 feet. The force of gravity on Everest is about 0.434% less than the standard 9.8N/kg. This means that one pound at Sea Level […]
Is damped oscillation?
Is damped oscillation? An oscillator is anything that has a rhythmic periodic response. A damped oscillation means an oscillation that fades away with time. Examples include a swinging pendulum, a weight on a spring, and also a resistor – inductor – capacitor (RLC) circuit. What causes damped oscillation? a decrease in intensity of oscillations with […]
Does photoelectric current depend on frequency?
Does photoelectric current depend on frequency? Photoelectric effect can be explained as: it takes a specific energy to launch an electron from a metal surface. This energy is the work function which relies upon the metal. Electrons can pick up energy by collaborating with photons. Current is not dependent on the frequency of photons. What […]
How do you arrange negative numbers in ascending order?
How do you arrange negative numbers in ascending order? Arrange the following integers in ascending order, putting the smallest first. Look at the negative numbers first. The smallest negative number is -35, then -2. Then look at the positive numbers. How are numbers arranged in increasing or decreasing order? Suppose for example, 81, 97, 123, […]
