Answer:
P waves are the type of earthquake wave which can travel through both liquids and solids.
Explanation:
Energy can be transferred during earthquake in the form of waves. These waves are termed as seismic waves. Mostly seismic waves are classified as body waves and surface waves. The body waves have higher frequency compared to surface waves. And thus surface waves can only travel or propagate through the surface of planet and not through fluids. But body waves can travel through solids as well as fluids based on their types. So among the given options and one type of body waves is P waves.
P waves are also known as Primary waves and they can travel through both liquids and solids.

Answer: The entropy change of the surroundings will be -17.7 J/K mol.
Explanation: The enthalpy of vapourization for 1 mole of acetone is 31.3 kJ/mol
Amount of Acetone given = 10.8 g
Number of moles is calculated by using the formula:
Molar mass of acetone = 58 g/mol
Number of moles =
If 1 mole of acetone has 32.3 kJ/mol of enthalpy, then
0.1862 moles will have =
To calculate the entropy change for the system, we use the formula:
Temperature = 56.2°C = (273 + 56.2)K = 329.2K
Putting values in above equation, we get
(Conversion Factor: 1 kJ = 1000J)
At Boiling point, the liquid phase and gaseous phase of acetone are in equilibrium. Hence,
Answer:
Percent mass of KNO3 in solution = 11% (Approx)
Explanation:
Given:
Mass of KNO3 = 25 grams
Mass of H2O = 200 grams
Find:
Percent mass of KNO3 in solution
Computation:
Mass of solution = 25 + 200 = 225 grams
Percent mass of KNO3 in solution = [25/225]100
Percent mass of KNO3 in solution = 11.111%
Percent mass of KNO3 in solution = 11% (Approx)
