Hello my friend thank you
The density of ice is less than the density of water.
Fun fact: Water is the only known liquid that has this change it density.
Answer:
Explanation:
Hello there!
In this case, according to the given information, it turns out possible to set up the following energy equation for both objects 1 and 2:
In terms of mass, specific heat and temperature change is:
Now, solve for the final temperature, as follows:
Then, plug in the masses, specific heat and temperatures to obtain:
Yet, the values do not seem to have been given correctly in the problem, so it'll be convenient for you to recheck them.
Regards!
The Density Calculator uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). The calculator can use any two of the values to calculate the third. Density is defined as mass per unit volume.
Correct answer: Galvanic cell
Reason:
Following are the differences between Galvanic cell and electrolytic cell:
1. <span>Galvanic cell converts chemical energy into electrical energy , on other hand <span>electrolytic cell converts electrical energy into chemical energy.
2. In galvanic cell, </span></span><span>redox reaction is spontaneous and is responsible for the production of electrical energy. in electrolytic cell, t<span>he redox reaction is not spontaneous and electrical energy has to be supplied to initiate the reaction.
Thus, galvanic cell </span></span><span>refers to an electrochemical cell that produces an electric current</span>
