Type of thermometer is used to measure the boiling point of view. pick from mercury and alcohol. explain your answer

mercury is sensitive to heat and expands even at light increase in temperature

alcohol cannot be used to measure high temperature because it will change to gas easily

a) Recycling means treating things that have already been used so that they can be used again

b)As making new things from the recycled ones take less money,less energy and less of the Earth's resources also it reduces pollution.

c)Compost

d) Composting is a cheap and useful process of speeding up decay

answer:

1-In a mercury thermometer, a glass tube is filled with mercury and a standard temperature scale is marked on the tube. With changes in temperature, the mercury expands and contracts, and the temperature can be read from the scale. Mercury thermometers can be used to determine body, liquid, and vapor temperature

2-Throughout the universe, it's natural for energy to flow from one place to another. And unless people interfere, thermal energy — or heat — naturally flows in one direction only: from hot toward cold.

3-The thermal conductivity of brass is high i.e., brass is a good conductor of heat. So, when a brass tumbler is touched, heat quickly flows from human body to tumbler. Consequently, the tumbler appears colder, on the other hand wood is a bad conductor.

4-Average speed = Total Distance/total time taken

=> speed = 280/4

= 70

=> avg speed = 70km/hr

5-Distance=Speed×Time

When speed is 40 kmph

Distance traveled by car =40×9

=360 km

When speed is 60 kmph

Time taken to complete the journey =

60

360

=6 hours

6-

answer:

mercury thermometer is preferred over alcohol thermometer because mercury thermometer does not evaporate easily.it is smaller in size

Explanation:

too long,are u expecting me to solve your assignment,kid do it on your own please

Mercury is the only one in liquid state at room temperature. It's used in thermometers because it has high coefficient of expansion. Hence, the slightest change in temperature is notable when it's used in a thermometer. It also has a high boiling point which makes it very suitable to measure higher temperatures.
