You transfer a one liter of lemonade into a 2-liter size pitcher, and the lemonade fills up half the container. does the density of the lemonade change? next you transfer a liter of oxygen into a 2-liter size container, and the gas expands to fill the entire container. does the density of the oxygen change? finally, you take a ball of clay and flatten it out like a pancake. does the density of the clay change?

1. No

2. Yes

3. No

Explanation:

1. You transfer a one liter of lemonade into a 2-liter size pitcher, and the lemonade fills up half the container. Does the density of the lemonade change?

No, the density of lemonade doesn't change. The density is given by the amount of lemonade didn't change only volume of container changed which doesn't change the density of the lemonade. If there was a change in temperature or pressure than the density of lemonade would have been changed.

2. you transfer a liter of oxygen into a 2-liter size container, and the gas expands to fill the entire container. Does the density of the oxygen change?

Yes, the density of oxygen changed. For gases, the volume is always equal to the container that the gas is inside therefore if volume of container changes then the volume of gas changes. Since 1 liter of oxygen was put into 2 liter size container, its volume changed and hence its density.

3. you take a ball of clay and flatten it out like a pancake. Does the density of the clay change?

No, the density of clay doesn't change. Weather the clay is in the shape of a ball or pancake or any other shape, its mass and volume doesn't change which means that density doesn't change at all.

carefully examine the map above. based on your knowledge of colonialism in africa, the area attributed to belgium on this map is most likely the democratic republic of the congo.

omg stop xd you need to chi
