A water molecule consists of three atoms; an oxygen atom and two hydrogen atoms, which are bond together like little magnets.
An iron pot is made up of only one substance, iron. Iron is an element classified as a transition metal
Iron. Elementsare pure substances that are made up of one kind of atom. Pizza is not an element because it is a mixture of many substances. Water is a pure substance, but it contains two kindsof atom: oxygen and hydrogen.
Its a formula relating to specific heat capacity
Δθ refers to the change in temperature
Q refers to the energy neededto raise the temperature of an object by the change in temperature
m stands for the mass of tje object
c is the specific heat capacity which is the amount of energy needed to heat up an object per unit mass
Answer:
Increase in height from the ground.
Explanation:
Potential energy =mass×acceleration due to gravity×height.
P.E= mgh
This element would have 122 neutrons.
Atomic mass is the accumulation of neutrons and protons.
169 - 47 = 122.
Therefore, there are 122 neutrons.
