Are plant cells affected when water is scarce

boyakko [2]

<span>Water is vital to the existence of plant life. Not only do plants use it to keep their cells from drying out, but they need water to move nutrients and raw materials throughout their systems to areas where photosynthesis and seed production take place. When water stress occurs, whether caused by drought or root impairment, many invisible processes are affected.</span>

A researcher studying the nutritional value of a new candy places a 4.70 g 4.70 g sample of the candy inside a bomb calorimeter

Sauron [17]

Answer : The nutritional Calories per gram of the candy are, 5.36 calories

Explanation :

First we have to calculate the amount of heat.

$q=c\times \Delta T$

where,

q = heat = ?

c = specific heat = $43.90kJ/K$

$\Delta T$ = change in temperature = $2.41^oC=2.41K$

Now put all the given values in the above formula, we get:

$q=43.90kJ/K\times 2.41K$

$q=105.799kJ$

Now we have to calculate the heat for per gram of sample.

Heat = $\frac{105.799kJ}{4.70g}=22.51kJ/g=22510J/g$

Now we have to calculate the heat in terms of calories.

As, 1 nutritional Calories = 1000 calories

and, 1 calories = 4.2 J

As, 4.2 J = 1 calories

So, 22510 J = $\frac{22510J}{4.2J}\times \frac{1}{1000}cal=5.36cal$

Therefore, the nutritional Calories per gram of the candy are, 5.36 calories
