Answer
No you did not lose weight.
Explanation:
Weight is the force acting on an object, Gravity is a force on earth which does not apply to the moon so your weight may change depending in where you are but your mass will stay the same because mass measures the matter of an object ITSELF! Have a nice day....
During the Physical changes
Answer:
A. The rate of heat transfer through the material would increase.
Explanation:
To calculate the heat transfer in a heat exchanger you decide that there is not heat leakage to the surroundings, that means that magnitude of the two transfer rates will be equal. Any heat lost by the hot fluid, is gained by the cold fluid. The equation that describes this is Q = m×Cp×dT
Where:
heat = mass flow ×specific heat capacity × temperature difference
So if we increase the rate of flow of cooling water and the other variables that ypu can control remain the same, the result is that the rate of heat transfer through the material would increase, as it is stated in option a.
To estimate the number of ladybugs in the entire garden, Ajoy needs the dimension of the garden.
<h3>What is a dimension?</h3>
Dimensions in mathematics are the measure of the size or distance of an object or region or space in one direction.
Dimensional measurement is of fundamental importance for interchangeability and global trade.
Hence, to estimate the number of ladybugs in the entire garden, Ajoy needs the dimension of the garden.

Hello!
The molarity of the HBr solution is 0,172 M.
Why?
The neutralization reaction between LiOH and HBr is the following:
HBr(aq) + LiOH(aq) → LiBr(aq) + H₂O(l)
To solve this exercise, we are going to apply the common titration equation:
Have a nice day!
