You have 528 ml of coffee at 75°C, and you add to it 187 ml of milk at 25°C. What is the final temperature of the coffee plus milk, assuming that no energy is lost to the environment?

Step 1
Step 1: Use the formula Q = mcΔT to calculate the heat gained or lost by each substance, where Q is the heat gained or lost, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature. Show more…

If 29.5 g of milk at a temperature of 4.20°C is added to a 240-g cup of coffee at a temperature 88.0°C, what is the final temperature of the mixture? Assume coffee has a specific heat of 4.19 × 10³ J/(kg · K) and milk has a specific heat of 3.93 × 10³ J/(kg · K).

At a local convenience store, you purchase a cup of coffee, but, at 98.4°C, it is too hot to drink. You add 46.9 g of ice that is −2.2°C to the 248 mL of coffee. What is the final temperature of the coffee? (Assume the heat capacity and density of the coffee are the same as water and the coffee cup is well insulated.)

246 g of hot coffee at 86.0 degrees Celsius are placed in a 137 g mug at 20.0 degrees Celsius. The specific heat of coffee is 4.00 J/g°C, while that of the mug is 0.752 J/g°C. Assuming no heat is lost to the surroundings, what is the final temperature of the system: mug + coffee?
