Direction: Graph the heating curve of ethanol using the information given. Check off each item as you add additional information to your graph so that none is missed.  Background information of Ethanol: Boiling Point = 78 0C Melting Point = -114 0C Starting Temperature = -120 0C After two minutes, frozen cold ethanol starts to melt. It takes two minutes to melt completely. After eight more minutes, it begins to boil. It boils for six minutes. Heat is added for two more minutes until ethanol reaches 80 0C. Label “melting” where this takes place. Label “vaporization” where this takes place. Label “phase change” where a phase change occurs. Indicate where ethanol is only a SOLID, only a LIQUID, and only a GAS. Of the three phases, label which phase has: weakest IMF, strongest IMF, and medium IMF.

A certain type of ship has two tanks in its engine. Each tank contains a different type of fuel. when the engine turns on, the same amount of energy is transferred out of both fuels. why did fuel 1 change pahse, but fuel 2 stayed the same. what happened to molecules of both fuels

please read everything properly... Take 3 4 5 hrs but solve full accurate drawing on bond paper don't use chat gpt etc okk

hints: The flask will be filled with water (at a constant rate of 500 gallons per minute). It will take me exactly 10 minutes to escape from the chains. The diameter of the tank at 1 foot intervals. I am 5 feet 9 inches tall, and I'm pretty skinny so that you can ignore both my volume and the volume of the stool in your analysis. A gallon is equal to 0.13368 cubic feet.  You can think of the volume and the height of the water as functions of time. You can easily find an expression for V (t), and then use your expression for volume in terms of height to solve for h(t). after 10 minutes amount of water in the tank=66.84 ft3 t=69.3 minutes h(t)=e66.84t/100?  -1 h(10)=e66.84(10)/100?  -1=7.39 ft  Height of stool=1.64 ft Height of water in the tank=7.39 ft Questions: show work How fast is the water rising?  I would like to know how long I will have to hold my breath during the last part of the stunt.

please help me quickly I will vote your answer with high rate all please

Question 2 Quality (x) is the ratio of the mass of liquid to the total mass of the vapor in the mixutre. True False A Moving to another question will save this response.

Why will more heat be lost by the hot water than gained by the cold water?   a)Calorimeter will absorb some of the heat. (Always the same amount.)   b)Calorimeter will absorb some of the heat. (The greater the ΔT, the more of it will be absorbed by the calorimeter.)   c)Conservation of energy does not work in calorimeters.   d)We are using different amounts of hot and cold water.

Please help!!! (Will provide helpful ratings for correct solution)

What is the required diameter in meters of a cylindrical tank which has a length of 3 meters used for oil storage that will supply the engine for 5 days having a fuel consumption of 60Kg/hour at 27 degrees API? Please Answer # 9. If you can answer # 10 it will be appreciated much and rated high. Thanks!

The Weather Monitor. Your South American expedition splits into two groups: one that stays at home base, and yours that goes off to set up a sensor that will monitor precipitation, temperature, and sunlight through the upcoming winter. The sensor must link up to a central communications system at base camp that simultaneously uploads the data from numerous sensors to a satellite. In order to set up and calibrate the sensor, you will have to communicate with base camp to give them specific location information. Unfortunately, the group's communication and navigation equipment has dwindled to walkie-talkies and a compass due to a river-raft mishap, which means your group must not exceed the range of the walkie-talkies (3.0 miles). However, you do have a laser rangefinder to help you measure distances as you navigate with the compass. After a few hours of hiking, you find the perfect plateau on which to mount the sensor. You have carefully mapped your path from base camp around lakes and…

QUESTION 2 SOALAN 2 a) The DP Transmitter device is used to measure level as an inferential measurement. When installing the DP Transmitter in an open tank at HP tapping point at 0%, the lower range values (LRV) and upper range values (URV) for the transmitter must be determined in order to properly register 0% at the LRV and 100% at the URV liquid level. By referring to Figure 2, calculate the calibrated range with specific gravity, SG is 1.1 and height, H of the tank is 100mm. Peranti Pemancar DP digunakan untuk mengukur paras sebagai ukuran taabir. Apabila memasang Pemancar DP di tangki yang terbuka di HP titik tirus pada 0%, nilai julat yang lebih rendah (LRV) dan nilai julat atas (URV) untuk pemancar mesti ditentukan untuk daftarkan betul pada 0% LRV dan 100% URV. Dengan merujuk Rajah 2, hitungkan julat yang dikalibrasi dengan graviti spesifik, S.G adalah 1.1 dan ketinggian, H tangki adalah 100mm. Tank open to Atmosphere Махт. Level Liquid DP Transmitter Vented to Atmosphere Min.…

Task3

A dust particle is suspended in the air (floating due to a small updraft and its own low mass) when a powerful loudspeaker plays a very low note (2 Hz so it can’t be heard but you can actually see the speaker move!). How will the dust particle move as a result of the speaker 
being turned on? Question 3 options:   A)  The dust particle will move up and down.   B)  The dust particle will be pushed across the room.   C)  The dust particle will move in a circular path.   D)  The dust particle will move side to side.
