A glass jar is partially filled with 34 g of sand. Initially, the glass and sand are both at a temperature of 23. 5 °c. A sample of 305 g of liquid water with an initial temperature of 75. 0 °c is added to the jar and the final temperature of the sand, glass, and water is 70. 0 °c. Assume that heat is transferred only between the jar, sand, and water (ignore other surroundings).
