well figure it out your self its really easy because if u are smart like me you will know it....
Yes, it depends on the depth and lengths on both sides of the river
Mass does not change with temperature
Change in temperature = New temperature minus Old temperature.
50
The teamperature does not change
Depends on the flow of the river ,if it is a fast moving river the temperature would be in the 50's. It also depends on the geographical location of the river and the season.
yes
it depends on temperature of the air and where the water is coming from.
It is variable but close to the general weather temperature.
A change in temperature can change the rate of physical or chemical change.
Temperature is a physical phenomenon Change of temperature is a physical change.
You can find the change in temperature by subtracting the initial temperature from the final temperature. For example, if the initial temperature is 20 degrees Celsius and the final temperature is 30 degrees Celsius, the change in temperature would be 10 degrees Celsius (30 - 20 = 10).
