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).

The smokey mountains have over 2,100 miles of rushing mountain streams and rivers that flow through the park. in each mile lives a diverse community of native fish, amphibians, insects, and larvae, some of which are found only in the southern appalachians. park managers and scientific researchers test many factors such as fish populations, the watersheds and water tests to determine a) too many lizards are present b) the water quality of the stream c) rainwater is running into local streams d) if visitors to the park are overstaying their welcome
