How does heat transfer in water or air? Convection is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it. Convection above a hot surface occurs because hot air expands, becomes less dense, and […]
Why are there exceptions to periodic trends?
Why are there exceptions to periodic trends? Periodic Trend The atomic radius of atoms generally decreases from left to right across a period. There are some small exceptions, such as the oxygen radius being slightly greater than the nitrogen radius. Within a period, protons are added to the nucleus as electrons are being added to […]

Which sound travels the fastest?
Which sound travels the fastest? Of the three phases of matter (gas, liquid, and solid), sound waves travel the slowest through gases, faster through liquids, and fastest through solids. Let’s find out why. Sound moves slowest through a gas. That’s because the molecules in a gas are spaced very far apart. Can sound pass through […]
Is Half Life negative?
Is Half Life negative? It has a negative sign because the number of nuclei of the isotope will decrease over time. The rate of decay is equal to the number of the nuclei multiplied by a proportionality constant that depends on the exact isotope. Bauer shows the decay of radioactive nuclei as a function of […]

Why is specific heat capacity of water so high?
Why is specific heat capacity of water so high? Water’s high heat capacity is a property caused by hydrogen bonding among water molecules. When the temperature of water decreases, the hydrogen bonds are formed and release a considerable amount of energy. Water has the highest specific heat capacity of any liquid. Which has a higher […]
