A 15.6 g bullet traveling horizontally at 867 m/s passes through a tank containing 14.4 kg of water and emerges with a speed of 546 m/s.   What is the maximum temperature increase that the water could have as a result of this event?

A student drops two metallic objects into a 120-g steel container holding 150 g of water at 25°C. One object is a 194-g cube of copper that is initially at 83°C, and the other is a chunk of aluminum that is initially at 5.0°C. To the surprise of the student, the water reaches a final temperature of 25°C, precisely where it started. What is the mass of the aluminum chunk? 241.47 Your response is off by a multiple of ten. kg eBook

Scientists experiment with a balloon near a Himalayan fresh water lake at an altitude of 5000 m where atmospheric pressure is half of that at sea level. The temperature of the lake is uniform with depth and identical to the air at the surface of the lake. To what depth should a balloon be taken under the lake to reduce its volume by a factor of 4?   answer: 20m

The temperature of a 5.00-kg lead brick is increased by 525 C°. If the specific heat capacity of lead is 128 J/(kg.C°), what is the increase in the mass of the lead brick when it has reached its final temperature? O 5.80 × 10- -11 kg O 9.12 × 10-11 kg O 1.60 × 10-12 kg O 3.73 × 10-12 kg O 2.80 × 10-12 kg

A 5.60-g lead bullet traveling at 580 m/s is stopped by a large tree. If half the kinetic energy of the bullet is transformed into internal energy and remains with the bullet while the other half is transmitted to the tree, what is the increase in temperature of the bullet?

A 15.0 g bullet traveling horizontally at 865 m/s passes through a tank containing 13.5 kg of water and emerges with a speed of 534 m/s. What is the maximum temperature increase that the water could have as a result of this event?

A balloon filled with 3.50 kg of water at a temperature of 22°C is dropped from rest from an airplane. The airplane is 8000 m above the ground. There is air resistance acting on the balloon, and just before hitting the ground, the balloon is traveling at a speed of 200 m/s. For this problem, you can ignore the balloon material (its mass, specific heat etc…) and just treat the balloon as 3.50 kg of pure water. Also, assume g is a constant 9.8 m/s^2 during the entire fall and that the system of the water + surrounding air is a closed system. Assume that all internal energy change occurs in the water. a) Find the temperature of the water in the balloon just before hitting the ground.  ( cm, water = 4186 J/kgK)

Between 1793 and 1837, the U.S. penny was made entirely of copper and had a mass of 3.20 g. A coin collector accidentally drops one such penny from the balcony of his high-rise apartment, 36.0 m above the street. If 42.0% of the change in gravitational energy of the penny–Earth system is converted into internal energy of the penny, what is the increase in the temperature of the coin just before it impacts with the sidewalk? °C
