You are put on a wool sweater of approximately 1.5 kg, because it is around 30 °F  outside. The wool sweater was initially around room temperature of about 75 °F. It takes about 1.47 J of energy for the sweater to go from room temperature to the temperature outside. What is the specific heat capacity of the sweater? Please express the specific heat capacity in the unit of joules/kg.degrees Celsius

A person taking a reading of the temperature in a freezer in Celsius makes two mistakes: first omitting the negative sign and then thinking the temperature is Fahrenheit. That is, the person reads -x°C as X°F. Oddly enough, the result is the correct Fahrenheit temperature. What is the original Celsius reading? Round your answer to three significant figures. °C

An electronics device generates 30.5 W of heat energy during normal operation. The heat is dissipated from the top surface of the device to ambient air at 23°C. If the top surface area is 0.158 m2 and the convection heat transfer coefficient is 7.838 W/m2. K, what will be the surface temperature (in °C) of the device [round your final answer to one decimal place]? Air, T. T 00 S

A rectangular window in a home has a length of 1.5 m and a height of 0.80 m. If the window allows heat to escape from the  home at a rate of 2,000 watts, how thick must the window be if the inside temperature of the home is 220 C and the outside temperature is 3.00C? (Assume that the coefficient of thermal conduction of glass is 0.80 W/mK.)   a. 7.1 mm   b. 124 mm   c. 9.1 mm   d. 8.1 mm   e. 11 mm

An arctic weather balloon is filled with 40.7 L of helium gas inside a prep shed. The temperature inside the shed is 7.°C. The balloon is then taken outside, where the temperature is −11.°C. Calculate the new volume of the balloon.You may assume the pressure on the balloon stays constant at exactly 1atm. Round your answer to 3 significant digits.

A swimming pool filled with water has dimensions of 4.76 m ✕ 10.2 m ✕ 1.70 m. Water has density ρ = 1.00 ✕ 103 kg/m3 and specific heat c = 4186 J/(Kg◦°C). Find the mass (in kg) of water in the pool. 2. Find the thermal energy (in J) required to heat the pool water from 3°C to 27.1°C. 3. Calculate the cost (in dollars) of heating the pool from 3°C to 27.1°C if electrical energy costs $0.120per kilowatt-hour.

450g of water is heated in a pot from 22°C to 62°C. The water has a specific heat capacity of 4190 J/kg*K. What is the amount of thermal energy/heat transferred to the water to increase the temperature?

A slice of bread contains about 4.19 x 105 J of energy.  If the specific heat of a person is 4.19 x 103 J/kgCo, how many degrees Celsius would the temperature of a 70 kg person increase if all the energy in the bread were converted to heat? Group of answer choices 1.33 1.43 C 3.66 1.53 2.55 C

A thermos contains 155 cm³ of coffee at 88.8 °C. To cool the coffee, you drop two 13.1-g ice cubes into the thermos. The ice cubes are initially at 0 °C and melt completely. What is the final temperature of the coffee in degrees Celsius? Treat the coffee as if it were water. Number i Units

An underground gasoline tank can hold 1.19 x 10³ gallons of gasoline at 52.0°F. If the tank is being filled on a day when the outdoor temperature (and the gasoline in a tanker truck) is 97.0°F, how many gallons from the truck can be poured into the tank? Assume the temperature of the gasoline quickly cools from 97.0°F to 52.0°F upon entering the tank. Step 1 We will convert the initial and final Fahrenheit temperatures of the gasoline to degrees Celsius using Tc=(TF - 32.0). For the initial temperature in degrees Celsius, we have T₁,c=(52 X Your response differs from the correct answer by more than 10%. Double check your calculations. °F - 32.0 = 11.11 Your response differs from the correct answer by more than 10%. Double check your calculations. °C, and for the final temperature in degrees Celsius, we have X Your response differs from the correct answer by more than 10%. Double check your calculations. °F - 32.0 Your response differs from the correct answer by more than 100%.°C. 32.0)…
