You need to convert a temperature of 300 kelvin to energy units using Boltzmann's constant from scipy.constants. Which code snippet correctly calculates this energy in joules?
Afrom scipy.constants import K
energy = 300 * K
print(energy)
Bimport scipy.constants as sc
energy = 300 * sc.k
print(energy)
Cimport scipy.constants as sc
energy = 300 * sc.Boltzmann_constant
print(energy)
Dfrom scipy.constants import Boltzmann_constant as k
energy = 300 * k
print(energy)
Step-by-Step Solution
Solution:
Step 1: Identify the correct constant name for Boltzmann's constant
In scipy.constants, Boltzmann's constant is named k.
Step 2: Use the correct import and multiplication
import scipy.constants as sc
energy = 300 * sc.k
print(energy) uses sc.k multiplied by temperature correctly.
Final Answer:
import scipy.constants as sc
energy = 300 * sc.k
print(energy) -> Option B
Quick Check:
Correct constant name and usage = import scipy.constants as sc
energy = 300 * sc.k
print(energy) [OK]
Quick Trick:Use 'k' for Boltzmann's constant in scipy.constants [OK]
Common Mistakes:
MISTAKES
Using Boltzmann_constant instead of k
Incorrect import or attribute names
Confusing temperature and energy units
