When removing the objects from the oven, you accidentally touch each one with your hand. Rank these objects on the basis of how hot they feel. Rank from largest to smallest. To rank items as equivalent, overlap them.

Two objects, with different sizes, masses, and temperatures, are placed in thermal contact. In which direction does the energy travel? (a) Energy travels from the larger object to the smaller object. (b) Energy travels from the object with more mass to the one with less mass. (c) Energy travels from the object at higher temperature to the object at lower temperature.

Estimate how long it should take to bring a cup of water to boiling temperature in a typical 600-watt microwave oven, assuming that all the energy ends up in the water. (Assume any reasonable initial temperature for the water.) Explain why no heat is involved in this process.

A block has a temperature of 277 K. Heat could spontaneously flow from which of the following objects to the block? Choose all that apply. a) A counter top at 357 K b) A carpet at 177 K c) A rug at 324 K d) A wall at 246 K e) A brick at 361 K f) A board at 106 K g) A table 366 K h) A shelf at 277 K

Homework 3: Problem 9:   An electric coffeemaker has a 790-W heating element. The specific heat of water is 4.19 × 103 J/(kg⋅°C).   How long, in seconds, does it take the coffeemaker to heat 0.57 L of water from 18°C to 95°C, assuming all the heat produced by the heating element goes into the water?  Δt = ______

A piece of wood lying in the Sun absorbs more heat than a piece of shiny metal. Yet the metal feels hotter than the wood when you pick it up. Explain.

On a cold day, a metal fence post feels colder to the touch than a tree. This sensation of different temperatures is explained by the fact that   Group of answer choices the specific heat capacity of the wood in the tree is higher. the temperature of the tree is higher. the specific heat capacity of the metal is higher. the thermal conductivity of the metal is higher. the thermal conductivity of the wood in the tree is higher.

Hilda wanted to investigate the absorption of heat by three different types of fabric. The set-up for the investigation is shown. Which would be the independent variable in her investigation? O the temperature on the thermometer O the time the blow dryer was used O the type of material O the type of blow dryer Thermometer Fabric 50 -45 40 55 **** 0 3: 35 30 5 10 6 15- 20 25 کار

As ice melts in a drink, is the heat gained by the ice equal to the heat lost by the drink? If it is in an insulated cup (like styrofoam)? I tried to calculate the values and what I got for the heat lost by the drink was a much larger number than heat gained by the ice after it melts
