The temperature of an iceberg can vary, but it is typically around -10 to -20 degrees Celsius at the surface.
The change in temperature from 15°C to -5°C is a decrease of 20 degrees Celsius.
The geothermal gradient in the Earth's continental crust typically ranges from about 20 to 30°C per kilometer depth. This means the temperature increases by 20-30°C for every kilometer you go deeper into the Earth's continental crust.
The temperature gradient of an oil well refers to the change in temperature per unit depth below the surface. It varies depending on factors such as the geothermal gradient of the region and the specific characteristics of the well. Generally, the temperature gradient in oil wells ranges from 0.02 to 0.05°C per meter of depth.
The increase in temperature caused the density of the water to decrease. As the temperature rose from 4°C to 20°C, the volume of the water expanded slightly while the mass remained constant. This resulted in a lower density at the higher temperature.
The term for the increase in temperature with depth in the Earth is called geothermal gradient. This gradient is typically around 25-30°C per kilometer in the Earth's crust.
The temperature can be as high as 15 to 20 C degrees (35-55) degrees.
The specific heat capacity of silver is 0.235 J/g°C. To raise the temperature of 3 g of silver by 5 °C (from 15 to 20°C), you would need 3 g x 5 °C x 0.235 J/g°C = 3.525 J of energy.
The increase in temperature with depth in the Earth is called the geothermal gradient. This gradient varies depending on factors such as location and geology, but typically averages around 25-30°C per kilometer depth.
Average temperature in Oslo from June-August is between 15-16 C
