Answer:

Reduce, reuse, and recycle your waste and trash. Protecting the environment helps protect the wetlands, especially since trash can make its way into the water. The best and easiest way to protect the environment is by limiting your household waste.

A sample contain 33.42g of metal pellets are poured on to a graduated cylinder initially containing 12.7ml of water, causing the

Answer:

3. 76 g/ml^3

Explanation:

We are given the mass of the metal pellets which is 33.4 grams. To calculate the density of the metal, we need to divide the mass by the volume. The volume of the metal is not directly given so we need to find it ourselves. The water was initially 12.7 ml and then it rose to 21.6 ml after placing the metal pellets. This indicate that the volume of the metal pellets is 8.9 ml.

$21.6 - 12.7 = 8.9$

We can now use the density formula.

$p = \frac{m}{v}$

$p = \frac{33.42}{8.9}$

$p = 3.76$

A) How much energy would be required to melt 500 grams of ice at 0°C to water at 0°C?

baherus [9]

Heat required = Q = 40 kcal

<h3>Further explanation</h3>

Given

mass of 500 g ice

Required

Heat required

Solution

The heat to change the phase can be formulated :

Q = m.Lf (melting/freezing)
Q = m.Lv (vaporization/condensation)

Lf=latent heat of fusion

Lv=latent heat of vaporization

Lf for water = 334 kj/kg=6.01 kJ/mol = 80 cal/g

Phase change(ice to water)

Q= 500 g x 80 cal/g

Q = 40 kcal
