A camper takes a 100-gram piece of basalt rock from a campfire and places it in a cup holding 250 mililiters of water. The temperature of the rock is 300C and the temperature of the water is 20C. Air temperature is also 20C. In the process of heating the water with the basalt, the temperature of the basalt decreased more than the temperature of the water increased. This difference most likey occured because

Answers

Answer:

This difference most likely occurred because the specific heat of water is higher than that of basalt.

Explanation:

Basalt is a fine-grained, dark-colored igneous rock that is mostly made up of plagioclase and pyroxene minerals.

Water is a gaseous, liquid, or solid substance made up of the chemical elements hydrogen and oxygen, and it can exist in gaseous, liquid, and solid states.

Basalt can be used to heat water. But when the specific heat of water is higher than that of basalt, the temperature of the basalt will drop more than the temperature of the water will rise when the water is heated with the basalt.

Therefore, this difference most likely occurred because the specific heat of water is higher than that of basalt.

Calculate the area of a map whose length is 6cm and width is 4cm the map scale is 2cm to 1km or 1:50,000

Answers

Answer:

12 km

Explanation:

Calculating the area of a map is very simple, you just need to multiply the length of that map by its width. In this case, you need to multiply 6 cm by 4 cm, the result will be 24 cm.

However, it is necessary that you convert this result according to the scale that the map presents. If this scale is 2cm to 1km, you will only need to divide 24cm by 2cm, which will convert the map area to kilometers. In this case 24/2 is equal to 12 kilometers. That's your result.
