Answer:
Explanation:
We are asked to find the energy given mass, specific heat, and change in temperature. Therefore, we must use this formula;
The mass is 15 grams and the specific heat is 0.129 J/(g×°C). Let's calculate the change in temperature.
- ΔT= final temperature - initial temperature
- ΔT= 85 °C- 22°C = 63°C
Now we know all the values:
Substitue the values into the formula.
Multiply the first numbers together. The grams will cancel.
Multiply again, this time the degrees Celsius cancels.
<u>121.905 Joules</u> are required.
A commodity that someone would invest in would be tea, coffee, and wine. Some of the more popular items people usually think of as a commodity.
Answer:
Because water exhibits cohesive behavior.
Explanation:
Cohesive behavior can be explained as a behavior where molecules are attracted to each other.
And this means that, water molecules are attracted to each other because of their cohesive behavior. This makes them to be attracted to other substances, such as the walls of the xylem of plants.
In this case, it is believed that the water molecules behave this way because they are polar, that is, there is an electronegativity difference between the bonded atoms. And this enables it to move from the roots to the leaves of the plants.
