What is the Final Temperature of the White Coffee?

In summary, a person adds 100 g of milk at 280 K to 300 g of black coffee at 350 K in a vacuum flask. Assuming equal specific heat capacities, the temperature of the white coffee after adding the milk can be calculated using the equations C = Q/ΔT and T = (m1*C1*T1 + m2*C2*T2) / (m1*C1 + m2*C2). However, since the specific heat capacities are not given, the problem cannot be solved.

Homework Statement


A person has 300 g of black coffee at temperature 350 K in a vacuum
flask. 100 g of milk at 280 K are added to the coffee (the flask is immediately closed, so the loss of heat to the air is negligible). Assuming that the specific heat capacities of the coffee and milk are equal, calculate the temperature of the white coffee (black coffee + milk) after the milk has been added.


Homework Equations


C = Q/ delta T
T = m1*C1*T1 + m2*C2*T2 / M*C2 + m1*C1

The Attempt at a Solution



This is where I am going mad I am not given specific heat capacities thus I have no idea as too how to go about solving this problem.

If C1=C2, then you can factor all those terms out...

FAQ: What is the Final Temperature of the White Coffee?

What is the cause of temperature change?

The primary cause of temperature change is the increase in the concentration of greenhouse gases in the Earth's atmosphere. These gases, such as carbon dioxide, trap heat from the sun and prevent it from escaping into space, leading to a rise in global temperatures.

How does temperature change affect the environment?

Temperature change has a significant impact on the environment, including melting of polar ice caps, rising sea levels, changes in precipitation patterns, and increased frequency and intensity of extreme weather events. It also affects plant and animal life, disrupting ecosystems and threatening biodiversity.

Is temperature change a natural process?

While some fluctuations in temperature are natural, the current rate of temperature change is far beyond the natural variation. The rapid increase in temperature over the past century is primarily due to human activities, such as burning fossil fuels and deforestation.

What are the potential consequences of temperature change?

The consequences of temperature change are far-reaching and can have devastating effects on human societies, economies, and the environment. These include food and water shortages, displacement of populations, increased spread of diseases, and loss of habitats and species.

What can be done to address the temperature change problem?

To mitigate the effects of temperature change, we need to reduce our greenhouse gas emissions by transitioning to clean and renewable sources of energy, implementing energy-efficient practices, and promoting sustainable land use. It also requires international cooperation and individual actions, such as reducing our carbon footprint and advocating for climate policies.
