A melting ice is caused by another element breaking up the atoms and making the move
The answer is B. making sawdust.
Because, to make sawdust you have to shred wood and you can't reverse that. Therefore, making sawdust is irreversible.
Answer:
75.2 degree Fahrenheit was the predicted high temperature.
Explanation:
Predicted high temperature in the Spain = T' = 24°C
In Spain temperatures are measured in Celsius. But we have to calculate the temperature in Fahrenheit .
To convert this temperature into Fahrenheit, we use the conversion factor:
75.2 degree Fahrenheit was the predicted high temperature.
Answer:
Trabalho realizado por máquina térmica = 250 J
Explanation:
Dado
Eficiência da máquina térmica = 5% = 0,05
A eficiência é igual à proporção do trabalho realizado pela máquina térmica para o calor fornecido a ela
Por isso,
0,05 = Trabalho realizado por máquina térmica / 5000 J
Trabalho realizado por máquina térmica = 5000 J * 0,05 = 250 J
Answer:
[K₂SO₄] = 2.50 M
Explanation:
We define the moles of solute: 6.01 mol of K₂SO₄
We define the solution's volume: 2.40L
To find out molarity we can make this rule of three:
In 2.40L of solution we have 6.01 moles of sulfate
Then, in 1L we have (6.01 . 1) / 2.4 = 2.50 M
Molarity is a sort of concentration that indicates the moles of solute in 1L of solution
