It happens so because,
we know that evaporation is a surface phenomenon. If surface area is increased, the rate of evaporation increases. That's why when we pour hot water in a plate it cools faster.
Answer:
The symbol for an atom can be written to show its mass number at the top, and its atomic number at the bottom. To calculate the numbers of subatomic particles in an atom, use its atomic number and mass number: number of protons = atomic number. number of electrons = atomic number.
Explanation:
Divide 67.6% by 201 of mercury
Divide 10.8% by 32 of sulfur
Divide 21.6% by 16 of oxygen
Then divide number by itself .
Example : Divide 2.97 by both sulfer moles and oxygen moles . Multiply by 2 to get whole number
Answer:
The potential energy the apple had due to its height is converted to kinetic energy
Explanation:
When an apple falls from the tree to the ground, its <u>energy of position stored as gravitational potential energy is converted to kinetic energy</u>, the energy of motion, as it falls. When the apple hits the ground, kinetic energy is transformed into heat energy.
