The weight of an object never changes. A. True B. False

Chemistry
2 answers:
Shalnov [3]2 years ago
6 0

Answer: false .

Explanation: Weight is the measure of the force of gravity on an object. The mass of an object will never change, but the weight of an item can change based on its location.

For example, you may weigh 100 pounds on Earth, but in outer space you would be weightless.Mass never changes. Weight, which is a product of mass times gravity, may change due to a difference in gravity

Answer:

\huge\boxed{\textbf{False}}

Explanation:

<u>Definition of weight:</u>

  • The gravitational force acting on a body is called weight.

<u>Explanation:</u>

The weight of the body changes with different factors concerned e.g. height h, acceleration due to gravity g etc.

We know that,

W = mg

Mass is a constant quantity, however g changes with the altitude or place. Consequently, weight also does not remain constant.

<u>Example:</u>

An object having mass 1 kg will have a weight of 9.8 N on Earth while its weight on moon will be 1.6 N due to the difference in the values of g.

At a festival, spherical balloons with a radius of 170.cm are to be inflated with hot air and released. The air at the festival
MissTica

Answer:

The correct answer is 1.5 balloons.

Explanation:

Based on the given question, the radius of the spherical balloons is 170 cm. Therefore, the volume of each balloon will be,  

= 4/3 × π × (170)³ cm³

= 20.5176 × 10⁶ cm³  

= 20.5176 m³

The density of air at 100 degree C s 0.946 Kg m⁻³

The mass of air in each balloon can be calculated by using the formula,  

Mass = density × volume

Mass = 0.946 Kg m⁻³ × 20.5176 m³

Mass = 19.410 Kg

The heat energy, that is, required to bring the air from 25 degree C to 100 degree C will be,  

= 19.410 × 10³ g × (100 -25) degree C × 1.009 J/g degree C

= 14.68 × 10⁵ J

The concentration of butane given is 1.00 Kg or 1000 g

The molecular weight of butane is 58.12 g per mole

The moles or n can be calculated by using the formula,  

n = mass / mol.wt

n = 1000 g/58.12 g/mol = 17.20 mol

The formation of enthalpy of butane at 25 degree C is 125.7 × 10³ J/mol. The evolution of heat energy that take place at the time of burning 17.20 moles of butane is,  

= 125.7 × 10³ J/mol × 17.20 mol

= 2.16 × 10⁶ J

The number of balloons that can be inflated with hot air is,  

= 2.16 × 10⁶ J / 14.68 × 10⁵ J per each balloon

= 1.5 balloons

Hence, maximum of 1.5 balloons can be inflated.

You are given an unknown type of clothing dye. how could you use the procedures in this lab to see if this dye is a mixture?
Arte-miy333 [17]
One separation technique to be used is the paper chromatography. This works by separating the components of the mixture through the difference of their concentrations. There is a stationary phase and the mobile phase, which flows through the stationary phase. The components travel at different rates and is usually signified by the colors. If more than one color would appear, that means that the dye is a mixture.
