Answer:
V2 = 4.5 dm³
Explanation:
Dados los siguientes datos;
Volumen inicial = 3 dm³
Temperatura inicial = 20°C Temperatura final = 30°C
Para encontrar el nuevo volumen V2, usaríamos la ley de Charles.
Charles afirma que cuando la presión de un gas ideal se mantiene constante, el volumen del gas es directamente proporcional a la temperatura absoluta del gas.
Matemáticamente, Charles está dado por;
Dónde;
V1 y V2 representan los volúmenes inicial y final respectivamente.
T1 y T2 representan las temperaturas inicial y final, respectivamente.
Haciendo V2 como la fórmula del sujeto, tenemos;
V2 = 4.5 dm³
Answer:
you supposed to do 70%-30%=40%
Explanation:
Answer:
O
Explanation:
Matters exist majorly either as solids, liquids or gases. These are called states of matter. A change of state occurs when a substance either absorb or release energy.
Since the atoms of the substance lost energy and become close together with the ability to slide past one another, the change of state is from gaseous to liquid. And the process is called condensation (O). Thus the process is that of O, called condensation.
The average velocity of the Batman is 0.722 m/s North-East.
<h3>What is average velocity?</h3>
Average velocity can be defined as the ratio of the total displacement to the total time of a body.
To calculate the average velocity of Batman, we use the formula below, first, we need to calculate the resultant displacement of the Batman.
- D = √[(d₁-d₃)²+ (d₂)²]............... Equation 1
Where:
- d₁ = first displacement of the Batman = 6 m North
- d₂ = second displacement of the Batman = 3 m East
- d₃ = third displacement of the Batman. = 4 m south
Substitute these values into equation 1
- D = √[(6-4)²+3²]
- D = √(2²+3²)
- D = √(4+9)
- D = √13
- D = 3.61 m North-East.
To calculate the average velocity, we use the formula below.
- V = D/T............ Equation 2
Where:
- D = 3.61 m North-East
- T = total time = 15 s
Substitute these values into equation 2
- V = 3.61/5
- V = 0.722 m/s North- East.
Hence, the average velocity of the Batman is 0.722 m/s North-East.
