if a metal object was cut on half how much heat will be required to raise both half to a specific temperature

Physics

3 0

suppose the mass of a metal object be m and its specific heat capacity be s, and, H joules of heat is required to raise its temperature by t degrees Celsius

Than H is given by relation, H = mst

Now if this object is cut in two half's, than mass of half part will also be half <em>i.e. </em>M/2

So heat required to heat the half part will be = (\frac{m}{2}) st =\frac{mst}{2} = H/2  

Hence, the heat required to raise the half object to a specific temperature will also become half.

Distinguish between atoms and molecules,
Lisa [10]
An atom is the smallest particle of an element which can take part in a chemical reaction

A molecule is the smallest particle of a substance that can normally exist alone and still retain the chemical properties of that substance, Be it an element or a compound.

Isotopic mass is the mass of an isotope of an element

Atomic mass is the mass of an atom.The relative atomic mass,A of an element is the number of times the average mass of one atom of that element is heavier than one-twelfth the mass of one atom of carbon-12

Molecular mass is the mass of a given molecule. The relative molecular mass,M, of an element or a compound is the number of times the average mass of one molecule of it is heavier than one-twelfth the mass of one atom of carbon-12

One mole of a substance is the amount containing as many elementary entities as the number of atoms in exactly 12 grams of Carbon-12 .

The molar mass of any substance is the mass of one mole of that substance expressed in grams

Donna wants to calculate the speed at which a sound wave is traveling. She knows that the frequency of the wave is 680 hertz and
Anettt [7]

f = frequency of the sound wave = 680 hertz

λ = wavelength of the sound wave = 0.5 meters

v = speed of sound wave

we know that , speed of sound wave is given as

speed of sound wave = frequency of sound wave x wavelength of sound wave

v = f λ

inserting the above values in the formula above

v = (680 hertz) (0.5 meters)

v = 340 meter/second


hence the speed of sound wave comes out to be 340 meter/second
