Problem: If you push an object with a constant force of 100 N over a 10-meter distance. How much energy transfer occurs on the o
Sveta_85 [38]

The energy transferred on the object is 1000 Joules.

Given:

An object on which a constant force of 100 N was applied to displace it over a distance of 10 meters.

To find:

The energy transfer occurs on the object.

Solution

The force applied on the object = F = 100 N

The displacement of the object = d = 10 m

The energy transferred on the object or work done is given by:

W = F\times d\\W=100 N\times 10 m = 1,000 J

The energy transferred on the object is 1000 Joules.

a solution containing 80 g of KCL in 200 g of H2O at 50 degrees celcius is cooled to 20 degrees celcius. How many grams of KCL r
Varvara68 [4.7K]

Answer:

12g KCl will be crystallized

Explanation:

To solve this problem you need to know solubility of KCl in water at 20°C is 34g per 100g of water.

That means the maximum concentration of KCl you can dissolve at 20°C in 200g of water is 34g×2 = 68g of KCl

As solution containing 80g of KCl, the extra KCl will be crystallized after cooling, that is:

80g of KCl - 68g of KCl = <em>12g KCl will be crystallized</em>

I hope it helps!
