Plants maintain water balance by opening and by closing stomata.

Explanation:

When plants are not getting enough water the tips as well as the edges of the leaves start drying and ultimately it turns brown in color. And when all the leaves turn brown the plant ultimately dies.

When light is travelling from the air to the water , the movement slows down and thus there is a little change in the direction. Thus we can say a light bend occurs when the light moves towards denser medium.

3. How does heat travel by conduction? ​
asambeis [7]

Conduction is the movement of heat through a substance by the collision of molecules. At the place where the two object touch, the faster-moving molecules of the warmer object collide with the slower moving molecules of the cooler object.

If you have a 4.6 L of gas in a piston at a pressure of 1.2 atm and compress the gas unit it's volume is 2.6 L, what will the ne
klio [65]

Answer:

<h3>The answer is 2.12 atm</h3>

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

P_1V_1 = P_2V_2

Since we are finding the new pressure

P_2 =  \frac{P_1V_1}{V_2}  \\

So we have

P_2 =  \frac{4.6 \times 1.2}{2.6}  =  \frac{5.52}{2.6}  \\  = 2.1230769...

We have the final answer as

<h3>2.12 atm</h3>

Hope this helps you

A solid piece of lead has a mass of 23.94g and a volume of 2.10cm^3. from these data, calculate the density of lead in si units
jeyben [28]
A density of a substance is constant. It is an extensive property, meaning it does not depend on the amount of substance because it is a ratio of mass to volume. No matter how much of each there is, they would always have a fixed ratio called density. For lead, the density is

Density = mass/volume
Density = 23.94 g/ 2.10 cm³
Density = 11.4 g/cm³

Determine the equilibrium pH and speciation (concentration of each species) of the following two solutions. Neglect activity cor
irina [24]

Answer:

HCl solution - H30+ and Cl ions. pH 3

NaCl - Na+ and Cl-. pH 7

Explanation:

a) HCl solution - the hydrogen ion combines with water molecule to form the hydronium molecule which is responsible for acidity. The chloride ion is also found in solution.

pH = -log [H+] = -log(10^-3) = 3

b) NaCl 10-3 g. The solid dissocates in water forming the Na+ and Cl- ions. None of these ions affect pH
