Answer:
30 °C
Explanation:
When you pour water from one glass to the other, the heat energy will flow from the hot water to the cold.
You have equal masses of water in each glass. The hot water should cool down as much as the cold water warms up.
The final temperature should be halfway between the starting temperatures in each glass.
(10 °C + 50°C)/2 = 60 °C/2 = 30°C
The temperature of the full glass of water should be 30 °C.
So, when two different air masses meet, a boundary is formed. The boundary between two air masses is called a front. Weather at a front is usually cloudy and stormy. There are four different fronts- Cold, Warm, Stationary, and Occluded.
Answer:
Since the middle of the 19th century, minerals have been classified on the basis of their chemical composition. Under this scheme, they are divided into classes according to their dominant anion or anionic group (e.g., halides, oxides, and sulfides).
Explanation:
Apart from the free gases in Earth’s atmosphere, some 20 elements occur in nature in a pure (i.e., uncombined) or nearly pure form. Known as the native elements, they are partitioned into three families: metals, semimetals, and nonmetals. The most common native metals, which are characterized by simple crystal structures, make up three groups: the gold group, consisting of gold, silver, copper, and lead; the platinum group, composed of platinum, palladium, iridium, and osmium; and the iron group, containing iron and nickel-iron. Mercury, tantalum, tin, and zinc are other metals that have been found in the native state.
The volume occupied by the argon gas is, 1.44 L
Explanation :
To calculate the volume of argon gas we are using ideal gas equation:
where,
P = pressure of argon gas = 1528 torr = 2.010 atm
Conversion used : (1 atm = 760 torr)
V = volume of argon gas = ?
T = temperature of argon gas = 
R = gas constant = 0.0821 L.atm/mole.K
w = mass of argon gas = 4.24 g
M = molar mass of argon gas = 39.95 g/mole
Now put all the given values in the ideal gas equation, we get:
Therefore, the volume of occupied by argon gas is 1.44 L
Answer:
The correct answer is "A consumer is obtaining carbon by eating carbon-based molecules stored in a producer".
Explanation:
The animal is consuming the carbon present in the molecules stored in the grass. Plants process the carbon present in the soil along with other minerals. The animal, when it feeds on these plants, is consuming the carbon they obtained from the soil. Grasslands are defined largely by their use for grazing, which includes between 10 and 30 percent of soil carbon worldwide.
Have a nice day!
