Chemistry
1 answer:
Oduvanchick [21]3 years ago
4 0

Answer: D. When the independent variable is continuous and shows a causal link to the dependent variable.

Explanation: Line graphs are usually very useful in visualizing relationships between variables (dependent and independent variable). Line graphs produce a very simple plot of these variables, however, by mere visualizing a line graph, one can tell if there exist a causal relationship between the measured variables. The independent variable when creating line graphs are real numerical values which should be continuous, aligning with the trend line produced by the graoh.

If 1,079.75 Joules of heat are added to 77.75 grams of water, by how many degrees Celsius would the water increase? Assume water
djyliett [7]

Answer:

If 1,079.75 Joules of heat are added to 77.75 grams of water, by 3.32 degrees Celsius the temperature of  water will increase

\Delta T=3.32 C^{0}

Explanation:

q = mC\Delta T

Here , q = heat added / removed from the substance

m  = mass of the substance taken

\Delta T = Change in temperature

C = specific heat capacity of the substance

In liquid state the value of C for water is :

4.18 J/gC^{0}

Given values :

q = 1079.75 J

m = 77.75 gram

Insert the value of C, m , q in the given equation

q = mC\Delta T

on transposing ,

\Delta T=\frac{q}{mC}

\Delta T=\frac{1079.75}{77.75\times 4.18}

\Delta T=3.32 C^{0}

How much energy is required to evaporate grams of water?.
gregori [183]

Answer:

energy known as the latent heat of vaporization is required to break the hydrogen bonds. At 100 °C, 540 calories per gram of water are needed to convert one gram of liquid water to one gram of water vapour under normal pressure.

Explanation:energy known as the latent heat of vaporization is required to break the hydrogen bonds. At 100 °C, 540 calories per gram of water are needed to convert one gram of liquid water to one gram of water vapour under normal pressure.
