Answer:
100 ml = 0.1 L
I divided 100 by 1000 because 1000ml = 1L
Answer:
20790 J
Explanation:
From the question given above, the following data were obtained:
Mass (M) = 165 g.
Initial temperature (T1) 10 °C.
Final temperature (T2) = 40 °C.
Specific heat capacity (C) = 4.2 J/g °C.
Heat (Q) required =?
Next, we shall determine the change in temperature of water. This can be obtained as illustrated below:
Initial temperature (T1) 10 °C.
Final temperature (T2) = 40 °C.
Change in temperature (ΔT) =?
ΔT = T2 – T1
ΔT = 40 – 10
ΔT = 30 °C
Finally, we shall determine the heat energy required to raise the temperature of the water as follow:
Mass (M) = 165 g.
Specific heat capacity (C) = 4.2 J/g °C.
Change in temperature (ΔT) = 30 °C
Heat (Q) required =?
Q = MCΔT
Q = 165 × 4.2 × 30
Q = 20790 J
Thus, the heat energy required to raise the temperature of the water is 20790 J
Answer:
Common uses of oxygen include production of steel, plastics and textiles, brazing, welding and cutting of steels and other metals, rocket propellant, oxygen therapy, and life support systems in aircraft, submarines, spaceflight and diving.
Explanation:
Oxygen is used to degrade hydrocarbon compounds, which are broken apart by heating them. This is used to create combustion that usually liberates water and carbon dioxide, but can also produce the hydrocarbons acetylene, propylene and ethylene. Oxygen is used in sewage-treatment and water-purification plants.
Answer:
// Program is written in C++ Programming Language
// Comments are used for explanatory purpose
// Program Starts here
#include<iostream>
using namespace std;
int main ()
{
// Declare Variables
int quarter, dimes, nickel, cent;
// Enter values for each
cout<<"Quarter: ";
cin>>quarter;
cout<<"Dimes: ";
cin>>dimes;
cout<<"Nickels: ";
cin>>nickel;
/*
In the United States, these coins have the following values
Quarter = 25 cents
Done = 10 cents
Nickel = 5 cent
Total cent is calculated below
*/
cent = 25 * quarter + 10 * dimes + 5 * nickel;
// Print Total
cout<<"The coins are worth "<<cent<<" cents";
return 0;
}
