What is the final equilibrium temperature when 15 grams of milk at 22 degrees Celsius is added to 185 grams of coffee at 86 degrees Celsius?

If coffee and milk have the same thermal coefficient then: (15*22 + 185*86)/200 = 81 (81,2 rounded off due to significant digits)

How hot is water from a boiling kettle?
100 deg C or 212 deg F at sea level. Water cannot exist in liquid form at normal atmospheric pressure at higher temperatures. The temperature of boiling water will go down as altitude increases. 100 degrees Celsius (Centigrade) or 212 degrees Fahrenheit AT SEA LEVEL. The higher the altitude, the lower the temperature at which water will boil. In a pressure cooker, water will boil at a higher temperature - depending on the pressure. In a microwave, water can become superheated without boiling if the vessel has no imperfections (for example, a china cup or glass in good condition). This is why, if you heat a cup of water for tea or coffee in a microwave for more than 2 minutes, and then add the tea bag or coffee, it will boil up and spill - possibly even explosively. Always take care!
Does temperature affect the solubility of coffee?
An increase in temperature will likely lower the pH of coffee. Coffee is already acidic, but increased temperature allows for more free ions in solution.
Why does iced coffee sweat on a hot day?
The air contains moisture (or water vapour) in varying amounts, depending on the humidity. A iced coffee - or anything else that is icy cold - has a temperature that is a lot colder than the surrounding air on a hot day.When hot air hits the side of a cup of iced coffee, it reduces the temperature of the air. When this occurs, the water vapour in the air condenses, forming the "sweat" (or water droplets) on the side of the cup.
Is coffee a acid or base?
Coffee is a nuteral
a 16.7 g polystyrene foam cup containing 31.0 mL coffee changes in temperature from 18 degrees celsius to 66.4 degrees celsius. calculate the heat absorbed by the cup and the coffee?

What is the temperature of a hot cup of coffee?
The average temperature of a cup of coffee should be served between 160 degree Fahrenheit and 185 degrees Fahrenheit. The liquids in this temperature range can cause significant scald burns.

What is the temperature for coffee?
130 degrees Fahrenheit
What is the temperature of hot coffee in Fahrenheit?
According to the National Coffee Association of USA, coffee should brewed at a temperature of 195-205 degrees F and served at 180-185 degrees.
What degree should coffee be held at?
coffee's temperature should be held at 80 degrees ferinhite
How hot is hot ice?
The average temperature of coffee is 160 degrees F. This converts to 71. degrees C. Coffee is also served at 185 degrees F which converts to 85 degrees C. At this temperature, scalding burns may occur.
Which has more thermal energy, a small cup of hot tea at 75 degrees Celsius or a large cup of hot coffee at 75 degrees Celsius?
the large one of course. because the more the mass is, the more the energy is.
Is 100 degrees hot or cold?
From a human perspective 100 K is extremely cold, equivalent to -173 degrees Celsius or -280 Fahrenheit. It is far colder than any temperature that would occur naturally on Earth. Temperatures that most people would find comfortable usually fall into the range of 290-300 K.
What temp should a expresso be brewed at?
According to the National Coffee Association of U.S.A., cold water should initially be used to brew coffee. Then, for optimal coffee extraction, the brewer should maintain a temperature of 195 - 205 degrees Fahrenheit (90 - 96 degrees Celsius). Lower temperatures will result in underextraction and a flat flavor. Higher temperatures will cause a loss of flavor quality.
What is the average temperature for hot tea or coffee in celsius?
Some Like it HotCoffee is beat brewed between 92oC and 96oC (197.6 - 204.8oF) Tea is a complex beverage and can be brewed at differing temperatures depending on the type:Green Teas: 180oF (80oC)Semi-Fermented teas: 195oF (93oC)Black Teas: 212oF (100oC)In either case, the temperature of tea or coffee as served will be 10oC or so less than the brewing temperature55-92 degree celsiusNoteThere is no maximum temperature set by Law. Following the whole McDonald's Coffee Case even McDonald's itself has not reduced the temperatures of their hot beverages- they still serve tea/coffe at 170ºF (77ºC).Starbucks serve their coffee hotter than McDonald's, at a temperature of 175 to 185 degrees F.
What is the final temperature when 0.032 kg of milk at 11 degrees Celsius is added to 0.16 kg of coffee at 91 degrees Celsius?
this is just a guess because both are mostly water, you would expect that the immediate final temperature would be 5/6 the way between 11 and 910C. So ~77.50C. Though because the mixing vessel is not warmed to this temp (heat capicity of calorimeter) along with the room temp playing a role, it will in practice be lower
