Answer:
Explanation:
In this problem,
we will determine the enthalpy at the end of heat input and we get the condition is the super heated state.
so the entropy change will be due to latent heat at 150 kPa and also due to temperature change at the super heated state.
All the temperature, enthalpy is evaluated with the help of the steam table.
mass is calculated with the help of a specific volume at initial condition.

Answer:
Up to 80 - 120 days.
Explanation:
The flower will probably stay six to twelve days or so.
I'm not sure what's your hypothesis going to be, but I'll give you an example.
" <em>If</em> I __________, <em>then</em> the sunflower will grow up to 80 to 120 days."
In the blank space, you can write what you're going to do to your sunflower during the experiment.
Please correct me if I'm wrong.
Organic molecule. In particular, a carbohydrate.
Answer:
A. Because they are compounds, they cannot be pure substances.
Explanation:
The false statement from the given choices is that because they are compounds they cannot be pure substances. In fact, because they are compounds they are pure substances.
Pure substances are made up of elements and compounds and they have the following properties:
- All parts are the same throughout
- Composition is definite
- They cannot easily be separated or broken
- Separation by physical method is not easy
- They have unique sets of physical and chemical properties.
