How much heat is required to raise the temperature of 67.0 g of water from its melting point to its boiling point?
vodka [1.7K]

When 67 g of water is heated from its melting point to its boiling point, it takes 28006 J of heat.

<h2>Relationship between heat production and temperature change</h2>
  • A way to numerically relate the quantity of thermal energy acquired (or lost) by a sample of any substance to that sample's mass and the temperature change that results from that is provided by specific heat capacity.

The following formula is frequently used to describe the connection between these four values.

q = msΔT

where, q = the amount of heat emitted or absorbed by the thing

m =  the object's mass = 67 gm

s =  a specific heat capacity of the substance = 4.18  J/gC

ΔT = the resultant change in the object's temperature = 373.15 -273.15K= 100 k

q = 67 * 4.18 * 100 J

⇒q = 28006 J

Therefore it is concluded that 67 g of water takes 28006 J of heat from its melting point to reach its boiling point.

List the number of protons neutrons and electrons in 13/6 C
Charra [1.4K]
<h3>Answer:</h3>

             Number of Protons =  6

             Number of Electrons  =  6

             Number of Neutrons  =  7

<h3>Explanation:</h3>

Number of Protons:

                               As the number of protons present in the nucleus are equal to the atomic number therefore, using periodic table one can easily find out the atomic number of C atom. Hence, C is present in group 14 and period 2 and having an atomic number of 6. Therefore, number of protons in C atom are 6.

Number of Electrons:

                                 As shown in statement, C is not carrying any type of charge. It means this atom is neutral in nature. Which means, it is carrying the same number of electrons as the number of protons in order to give a neutral atom. Therefore, it contains 6 electrons.

Number of Neutrons:

                                  Number of neutrons can be calculated using following formula,

                  No. of Neutrons  =  Atomic Mass - Number of Protons

As,

                                    Atomic Mass  =  13

So,

                                    No. of Neutrons  =  13 - 6

                                    No. of Neutrons  =  7
