As the yeast feeds on the sugar, it produces carbon dioxide. With no place to go but up, this gas slowly fills the balloon.

A very similar process happens as bread rises. Carbon dioxide from yeast fills thousands of balloonlike bubbles in the dough. Once the bread has baked, this is what gives the loaf its airy texture.

C. Describe the journey of a water molecule in a cloud as it makes its way to a lake. Include the movements and processes that t
nignag [31]
<h3><u>The journey of a water molecule in a cloud as it makes its way to a lake is explained below:</u></h3>
  • When the vapor in the cloud gets cold and cold then it changes back to a liquid form by the process called condensation.
  • When the vapor gets cold enough to convert into ice crystals, it condenses with the tiny particles of dust and smoke.
  • The sunlight warms the drop and evaporates it into the water vapor form.
  • These drops combines with other drops and forms a bigger one and falls to the earth with the help of gravity.

Demonstrate in a brief paragraph how the scientific method is used to help us understand the universe and the movement of planet
Zolol [24]

Answer: The scientific method attempts to minimize the influence of bias or prejudice in experiments. Even the best-intentioned scientists can't escape bias. That's the job of the scientific method. It provides an objective, standardized approach to conducting experiments and, in doing so, improves their results.

The Celsius temperature scale is also something called the centigrade scale. Why is this?
valentinak56 [21]
There are three temperature scales in use today, Fahrenheit, Celsius and Kelvin.

Fahrenheit temperature scale is a scale based on 32 for the freezing point of water and 212 for the boiling point of water, the interval between the two being divided into 180 parts. The 18th-century German physicist Daniel Gabriel Fahrenheit originally took as the zero of his scale the temperature of an equal ice-salt mixture and selected the values of 30 and 90 for the freezing point of water and normal body temperature, respectively; these later were revised to 32 and 96, but the final scale required an adjustment to 98.6 for the latter value.

Until the 1970s the Fahrenheit temperature scale was in general common use in English-speaking countries; the Celsius, or centigrade, scale was employed in most other countries and for scientific purposes worldwide. Since that time, however, most English-speaking countries have officially adopted the Celsius scale. The conversion formula for a temperature that is expressed on the Celsius (C) scale to its Fahrenheit (F) representation is: F = 9/5C + 32.


Hope this helps.
