- Problem 3: Newton's Law of Cooling states that the rate of change of the temperature of an object is proportional to the difference between the object's current temperature and that of its surrounding medium. Let y represent the temperature (in °F) of an object in a room whose temperature is kept at a constant 60°F. The object cools from 100°F to 90°F in 10 minutes. How much longer will it take for the temperature of the object to decrease to 80°F?arrow_forwardP3. After a particularly cold night, Alice leaves a tub of water outside. You may consider the ground and air to have temperatures of T. = -10°C and T = 10°C respectively. How thick is the layer of ice that forms at the bottom of the tub of water, after the tub has been left outside for a long time? The tub of water initially has a layer of water of thickness họ = 10 cm. You may assume that the ground and air remain at a constant temperature throughout, and that the side lengths of the tub a, b > ho, i.e. the heat conduction is one- dimensional. Density of ice and water are Pice = 920 kg/m³ and Pw = 1000 kg/m³. Ice and water have thermal conductivities of kice = 2.22 WK-1m-1 and kiw = 0.556 W K-1m-1.arrow_forward. The hottest temperature on a planet was 864°F recorded on Venus by the Soviet Venera probe and the U.S. Pioneer probe. The coldest place in the solar system is Pluto where the temperature is estimated at 1360.0°F. Calculate each of these temperatures in degrees Celsius.arrow_forward
- Suppose that a planet with no atmosphere orbits a Sunlike star at the same radius as the Earth’s orbit and keeps the same face toward the sun at all times. The planet reflects 40% of the light falling on it, and the average temperature on the facing surface is nearly uniform and 185 K larger than the nearly uniform temperature on its back surface. What is the planet’s average temperature? The planet's average planetary temperature is _______ K.arrow_forwardIn a warm room a naked resting person has a skin temperature of 33°C if the room temperature is 29° C, what is the body surface area if the rate of heat loss due to convection is 43watt and the convection constant K =7.1 watt /m?.K Choose the right answer: 1.8m? 1.5m2 O 1.7m2arrow_forwardResearchers are conducting a study to quantity the thermal conductivity of a composite material.
