Coffee Spoon
A silver spoon weighing 14.5 g if placed in a styrofoam cup containing 300 mL of hot coffee at 72 C.?
find the final temp of the coffee if the initial temp of the spoon is 3.00 C Assume that the coffee has the same density and specific heat capacity of water. The specific heat capacity of silver is . 23502 J/g C
Please show the work on how to do this problem. Thanks
Heat lost by the coffee = 300g x 4.184J/g/°C x (72 – T) ΔT°C.
= 90,374.4 – 1,255.2T.
Heat gained by spoon = 14.5g x 0.23502J/g/°C x T – 3).
= 3.41T – 10.223.
Heat lost = heat gained.
90,374.4 – 1,255.2T = 3.41T – 10.223
90,374.4 + 10,223 – 1,255.2T + 3.41T.
T = 90,384.6 / 1,258.6 = 71.8°C Final temp.

Vintage Recipe for a Delicious Apple Coffee Cake; Perfect for Apple Season
Fall is a time of cool air, beautiful colored leaves, and apples. What could be better on a cool, crisp fall morning or evening than a good cup of coffee and a fresh piece of this wonderful old-fashion apple coffee cake? This old recipe could have come straight from your grandmother’s little metal recipe box. Enjoy the warmth of good food and good memories on a cool fall or winter day.
6 apples, cored, pared, and sliced (about 3 cups)
5 tbsp + 2 cups sugar
5 tsp cinnamon
3 cups flour
2 cups sugar
3 tsp baking powder
1 tsp salt
1 cup salad oil
4 eggs
1/4 cup orange juice
1 tbsp vanilla
1/2 cup chopped nuts
Preheat oven to 375 degrees.
Combine sliced apples with the 5 tablespoons of sugar and the cinnamon. Set apples aside. Sift together flour, 2 cups sugar, baking powder, and salt into a mixing bowl. Make a well in center of flour and pour in the oil, eggs, juice, and vanilla. Beat till well blended. Brain the apple mixture of excess moisture. Spoon 1/3 of the batter into a greased 10-inch tube pan. Make a ring of 1/3 of the apple mixture on top of the batter, taking care not to have the apples touch the sides of the pan. Sprinkle 1/3 of nuts on top of the apples. Spoon another 1/3 of the batter on top of nuts and make another ring of apples and nuts. Top with remainder of batter, apples and nuts. Bake at 375 degrees for 1 1/4 hours or until done. Watch the top and if it is becoming too brown, cover lightly with aluminum foil. Cool cake to lukewarm before removing from pan. Enjoy!
