Note the number of protons, neutrons, and electrons in each of the following: #p^+ #n^8 #e^-' a, cobalt-60 b. potassium-40 c. carbon-14 a. Given a photon with frequency = 2.67 times 10^a s^-1, what is its energy? Ans. ___ b. If a different photon has frequency = 5.08 times 10^15 s^-1, will its energy be higher or lower than in 2a? Circle Higher or Lower Show the equation that lets you compare. c. Is the frequency of violet light higher or lower than the frequency of yellow light? d. Is the wavelength of violet light greater or less than that of yellow light? e. Is the energy of violet light greater or less than that of yellow light? a. Explain what is meant by the term 'Ideal Gas' including properties. b. Write the Ideal Gas Law ___ c. What is the volume of 1 mole of an ideal gas? ___Explanation / Answer
1.a) Cobalt-60 has 27 protons. 33 neutrons and 27 electrons
b) Potassium-40 has 19 protons, 21 neutrons and 19 electrons
c) Carbon-14 has 6 protons, 8 neutrons and 6 electrons
2.a) According to planck's equation Energy E = h = 6.626*10^-34*2.67*10^12
Therefore Energy E=1.769*10^-21 Joule
b) E = h, thus energy is directly proportional to the frequency.As given frequency is greater than the frequency in case a,the energy of photon is larger than in case of photon in question a.
c) Frequency of violet light is HIGHER than the frequency of yellow light.
d) Wavelength of violet light is LESS than that of yellow light.
e) Energy of violet light is Greater than that of yellow light.
3.a) A gas is said to be an IDEAL GAS , if it occupies a volume of 22.4 Litres of volume at a temperature of 273.15 K and 1 atm pressure.It follows ideal gas equation and assumptions of KInetic Theory of Gases.
b) Ideal Gas Law is PV=nRT
c) The volume of 1 mole of an ideal gas is 22.4 Litres.
