The temperature change for water in the 4-liter container will be

a.half that of the 2-liter container.

Explanation: -

The increase in temperature of a substance when heat is given to it is given by the formula

Q = m x c x ΔT

Where Q is the heat supplied, m is the mass of water, c is the specific heat of water and ΔT is the change in the temperature of water.

Or ΔT = $\frac{Q}{m x c}$

From the formula we see that for the same amount of heat, increase is temperature is more for less amount of mass.

We know that more the volume of water, more the amount of water present and consequently more the mass of water.

Thus for the same amount of heat supplied, the temperature increases more for a lesser volume of water.

Let density of water be d.

Mass of 4 L= volume x density = 4 L x d

T 1 = ΔT for 4 L = $\frac{Q}{m x c}$

= $\frac{Q}{4 L x d x c}$

Mass of 2 L= volume x density = 2 L x d

T2 = ΔT for 2 L = $\frac{Q}{m x c}$

= $\frac{Q}{2 L x d x c}$

On taking ratio

$\frac{T 2}{T 1}$ = 2

Thus the temperature change for water in the 4-liter container will be

a.half that of the 2-liter container.

For cyclohexane compounds drawn in a chair conformation: -axial bonds are vertical -equatorial bonds are parallel to two bonds within the ring. thus, as i assume the chair conformation is drawn: -the x group is in an axial position, as are the five other vertical bonds. -three axial bonds are on the top face of the ring -the other three axial bonds are on the bottom face the position of the second substituent on each ring carbon is equatorial. gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other. drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1. click this link and watch some academic videos that may you more understand the topic

One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(ii) carbonate, in concentrated sulfuric acid. the sulfuric acid reacts with the copper(ii) carbonate to produce a blue solution of copper(ii) sulfate. scrap iron is then added to this solution, and pure copper metal precipitates out because of the following chemical reaction: (s) (aq) (s) (aq) suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. he adds powdered iron to a copper(ii) sulfate sample from the plant until no more copper will precipitate. he then washes, dries, and weighs the precipitate, and finds that it has a mass of .

In november 1987, a massive iceberg broke loose from the antartic ice mass and floated free in the ocean. the chunk of ice was estimated to be 98 mi long, 25 mi wide, and 750 ft thick. a typical backyard swimming pool contains about 24,000 gallons of water. how many of these pools could you fill from the water in this iceberg? (assume the iceberg is a rectangular solid of the above dimensions and consists of water only). express answer in scientific notation.
