Answer:
Amount of gas
Explanation:
The combined gas law has to do with pressure, volume, and temperature. All of them can be a variable that you have to solve for. However, amount of gas is not a variable you can solve for, which means it must remain constant.
Answer:
The answer is
<h2>2.64 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 611 g
volume = final volume of water - initial volume of water
volume = 256.7 - 25.1 = 231.6 mL
The density of the metal is
We have the final answer as
<h3>2.64 g/mL</h3>
Hope this helps you
Answer:
A star is made up of burning gases, while a comet is made up of ice, gases, rocks, and dust.
Explanation:
The correct answer is - A- Amount of nitrogen in fertilizer.
The independent variable, in mathematical terms, is the variable whose variation is not dependent on the variations of the another variables.
In this case, the independent variable will be the amount of nitrogen in the fertilizer, as it is not dependent on any other variable. Also, apart from not being dependent on other variables, it is a variable on which the other variables are dependent, which in this case will be the amount of leaves and the amount of blossoms on the tomato plant.
Answer:
Amount of heat required = 2810.5 J
Explanation:
Given data:
Mass of copper = 29.2 g
Initial temperature = 25°C
Final temperature = 275°C
Amount of heat required = ?
Solution:
Specific heat capacity of copper is 0.385 j/g.°C.
Formula:
Q = m×c×ΔT
ΔT = 275°C - 25°C
ΔT = 250°C
Q = 29.2 g × 0.385 j/g.°C ×250°C
Q = 2810.5 J
