Answer:

it's physical change because none of the components of the bar of solid have been tampered with so solid to liquid is physical change

You have the same two resistors on a 10 volt series circuit. Will the voltage going into the second resistor be more, less, or t
Keith_Richards [23]

both resistance will have same voltage across it which is equal to 5 volt.

if resistance value is different then voltage drop across them will be different.

current in both resistance would be same.

let's say resistance is 5 ohm of each one.

total current = total voltage / total resistance

= 10 /(5+5) = 10/10 = 1 amp

now voltage across 5 Ohm resistance = current × resistance = 1× 5 = 5 volt

How to get the absolute zero from the graph for Charles law in Celsius? In this case what would be my value? Please help need it
k0ka [10]

At time t = 273.15 °C, the x-intercept occurs. According to Charles' law, an ideal gas's volume decreases as its temperature rises. At t = 273.15 °C, the graph's x-intercept, volume approaches zero.

<h3>Charles law experiment: what is it?</h3>

Describe the Charles Law experiment. Gases have a tendency to expand when heated, according to Charles' law (sometimes referred to as the law of volumes), an experimental gas law. The Kelvin temperature and the volume will be directly proportional when the pressure on a sample of the a dry gas is held constant, according to a current interpretation of Charles's law.

<h3>Which laws—Charles and Boyles—have similarities?</h3>

Boyle's law is formulated for systems with constant temperature, whereas Charles' law is formulated for systems with constant pressure.

<h2>Answer: O: 1s22s22p4</h2>

Explanation: In writing the electron configuration for oxygen the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for O go in the 2s orbital. The remaining four electrons will go in the 2p orbital. Therefore the O electron configuration will be 1s22s22p4.
