The difference between hypothesis and theory.

Answer to Problem 1Q
Theories are initiated from hypothesis.When one gives an explanation about a fact based on some observation, it is known as hypothesis and when a set of ideas are explained for a fact, it is known as theory.
Explanation of Solution
Introduction:
When a phenomenon is observed, a scientist tries to find a natural cause for its occurrence. If any existing theory cannot explain the phenomenon, he creates a hypothesis that can be experimentally tested.
Thereafter, a researcher plans and creates an experiment, which is performed to test the hypothesis and a conclusion is attained. Based on the conclusion, a theory can be proposed if the results obtained are reproducible and provides similar observation everytime.
Expalnation:
Following are some points which describe the difference between hypothesis and theory.
Hypothesis | Theory |
• It is a set of statements termed as an explanation for how a specific phenomenon occurs. | • It is an explanation about a natural phenomenon which is testable. |
• Verification of hypothesis is nothing but the theory. | • Theory can be verified by a number of experiments. |
• The hypothesis is a tentative description of observations. | • The theory is a principle which explains the observations. |
• Hypothesis justifies only a particular or single fact which is to be tested. | • Theory confirms the hypothesis and can be appliedto other circumstances. |
• The hypothesis is subjective. | • The theory is objective. |
Conclusion:
Thus, the hypothesis and theory are two inter-dependent concepts but different in nature. Theories are initiated from hypothesis.When one gives an explanation about a fact based on some evidence, it becomes hypothesis, and when a set of ideas are explained for a particular fact, it is theory.

- Question 6: Chlorine is widely used to purify municipal water supplies and to treat swimming pool waters. Suppose that the volume of a particular sample of Cl₂ gas is 8.70 L at 895 torr and 24°C. (a) How many grams of Cl₂ are in the sample? ⚫ Atomic mass of CI = 35.453 g/mol • Molar mass of Cl₂ = 2 x 35.453 = 70.906 g/mol Solution: Use the Ideal Gas Law: Step 1: Convert Given Values • Pressure: P = 895 torr → atm PV= = nRT 1 P = 895 × = 1.1789 atm 760 • Temperature: Convert to Kelvin: T24273.15 = 297.15 K • Gas constant: R = 0.0821 L atm/mol. K Volume: V = 8.70 L Step 2: Solve for n . PV n = RT n = (1.1789)(8.70) (0.0821)(297.15) 10.25 n = = 0.420 mol 24.405 Step 3: Calculate Mass of Cl₂ Final Answer: 29.78 g of Cl₂. mass nx M mass= (0.420)(70.906) mass= 29.78 garrow_forwardE1 R₁ w 0.50 20 Ω 12 R₁₂ ww ΒΩ R₂ 60 E3 C RA w 15 Ω E2 0.25 E4 0.75 Ω 0.5 Ωarrow_forwardSolve plzarrow_forward
