Translate please, i’d be able to help better:)
As a charge <span>u </span><span>moves through a resistor, it loses a potential energy uR where R is the potential drop across the resistor. which is converted to heat.
The formular for the P=uR=uR/t.</span>
Hi,
The correct answer is letter B.
The last group contains noble gases, while both along the top and along the bottom the elements on the right are non-metals.
The key difference between a bomb calorimeter and a coffee cup calorimeter is high temperature.
<h3>
What is bomb calorimeter?</h3>
A bomb calorimeter is an apparatus that can measure heats of combustion, used in various applications such as calculating the calorific value of foods and fuels.
<h3>What is coffee cup calorimeter?</h3>
A coffee cup calorimeter is a cup used to provide insulation when materials are mixed inside of it.
<h3>Difference between the two calorimeter</h3>
- The coffee cup calorimeter can't be used for high-temperature reactions, either, because they would melt the cup.
- A bomb calorimeter is used to measure heat flows for gases and high-temperature reactions

The formula you use is Density = (mass) / (volume) .
The calculation for this particular object is
Density = (68.895 g) / (23.5 mL - 14.7 mL)
Density = (68.895 g) / (8.8 mL)
<em>Density = 7.8 g/mL</em>
