The volume of 0.354g of helium at 273°C and 114cm of mercury pressure is 2667cm3. Calculate the volume?
A. 2000.25 cm³ B. 200.025 cm³ C. 4003.27 cm³ D. 2010.25 cm³ Correct Answer: Option B Explanation m = 0.354g, T1 = 273°C = 273 + 273 = 576K P1 = 114cmHg, V1 = 2667cm³ at STP T2 = 273K, P2 = 76cmHg, V2 = ? P1V1/T1 = P2V2/T2 V2 = (114 × 2667 × 273) / (76 × 576) =...When two objects A and B are supplied with the same quantity of heat, the temperature change in A is obtained to be twice that of B. The mass of P is half that of Q. The ratio of the specific heat capacity of A to B is
A. 1 : 4 B. 4 : 1 C. 1 : 1 D. 2 : 1 Correct Answer: Option C C. 1 : 1What are the units of latent heat?
The following are some units I. Ns II. Non III. Nm‾² IV. J°K‾¹ V. JKj‾¹ A. I B. II C. III D. V Correct Answer: Option D D. V Explanation Latent heat or specific latent heat = L Heat energy = mL or L = H/m =...A boy pushes a 500kg box along a floor with a force of 2000N. If the velocity of the box is uniform, the co-efficient of friction between the box and the floor is?
A. 1 A. 0.8 C. 0.65 D. 0.4 Correct Answer: Option D D. 0.4Products
