Please help i will give you 50 points what is the density of a book whose mass is 1,800 g and whose volume is 300 cm2
what is the mass of a ball whose density is 0.250 g/cm3 and whose is 200 cm3
Answers
Answer : The density of book is
The mass of a ball is, 50 grams.
Explanation :
Part 1 :
Density : It is defined as the mass contained per unit volume.
Formula used :
Given :
Mass = 1800 g
Volume =
Now put all the given values in the above formula, we get :
Therefore, the density of book is
Part 2 :
Formula used :
Given :
Volume =
Density =
Now put all the given values in the above formula, we get :
Therefore, the mass of a ball is 50 grams.
Answer: For your first question about the book, the answer is 6 g/cm^3. For the ball, your mass is 50 grams.
Explanation: density = mass/volume; for example: your book was 1,800 g. Divide that by 300 cm^3 to get 6g/cm^3. For the ball, mass = density*volume, so you need to multiply .250 by 200 cm^3

Answer: 5 grams of liquid water at 20°C will have more energy.
Explanation:
Kinetic energy is the measure of temperature of the system.
The equation used to calculate kinetic energy of a particle follows:
where,
E = kinetic energy of the particles
k = Boltzmann constant =
T = temperature of the particle
From the above relation, it is visible that kinetic energy is directly related to the temperature of the system.
If the temperature of the particles is high, it means that the particles will have more energy.
We are given:
5 grams of ice cubes at -10°C
5 grams of liquid water at 20°C
So, the temperature of water particles is more than the temperature of ice cube.
Hence, 5 grams of liquid water at 20°C will have more energy.

Final answer:
Endothermic reactions absorb energy from the environment and make it cooler, such as photosynthesis in plants, while exothermic reactions release energy into the environment and make it hotter, like burning wood in a fireplace.
Explanation:
Endothermic and exothermic reactions are different in terms of energy absorption and release. In an endothermic reaction, energy in the form of heat is absorbed from the surroundings into the system (reaction). This causes the environment to become cooler. An example would be the process of photosynthesis in plants.
In contrast, an exothermic reaction releases energy into the surroundings. As a result, the environment around an exothermic reaction heats up. An example of an exothermic reaction is combustion, such as the burning of wood in a fireplace.
