1270.cm of propane at 18.0°C are heated and allowed to expand to 1530.cm through an isobaric process. Calculate the final temperature in °C.
How many calories of heat need to be extracted from 200.g of steam at 120.°C to change it into ice at --12.0°C ?
Write a python program that splits a given string on a given split character. The first input is a String and the second input is the character that will be used to split the first String.
Answer the following problems
e. Consider a given bond that has five years maturity, Br.1000 face value and a 12 percent coupon rate. Suppose a broker’s commission of Br.50 is imposed by brokers to buy or sell the bond. Assume further, that the discount rate (minimum required rate of return) is 10 percent and the bond pays interest annually. What is the price of the bond?
f. Project X requires an immediate investment of $150,000 and will generate net cash inflows of $60,000 for the next three years. The project’s discount rate is 7%. If net present value is used to appraise the project, should Project X be undertaken?
Other than hydrogenation of benzene, take three reactions in which benzene reacts differently than the hypothetical 1,3,5-cyclohexatriene and explain the mechanism and reasons behind this
mechanism
The hypothetical heats of hydrogenation for 1,3,5-cyclohexatriene is different from the heats of hydrogenation of benzene. Explain this in detail.

4. Two shafts A and B are connected by rolling cones and turn in the same direction. Shaft A makes 300 rpm while shaft B makes 100 rpm. Calculate the cone angle of each cone and the diameter of each base if the base of cone B is 2 in. from the vertex. θ = 30°
3. Two shafts, having axes in the same plate intersecting at an angle of 45°, turn in opposite senses at 30 rpm and 90 rpm. Draw a pair of cone to be located on these shafts and turn in pure rolling contact. Diameter of base of smaller cone is 1 in. Calculate the cone angles.
2. Two solids of right section 2 and 4 are in pure rolling contact between the circular arcs. What is the angular speed ratio for the position shown? Determine the size of the angles , β, and Ø in degrees, and of the radii x and y in inches.
