Question

the difference between temperature and heat temperature is measured in degrees. it is not the same as heat, which is measured in joules. although an increase in heat causes an increase in temperature, the amount the temperature changes will vary, depending on the substance. the property of the amount of energy needed to raise the temperature of 1 kg of material by 1 degree k is called the specific - heat (c) and is expressed as j/kgk. specific heat varies for different materials. for example, the specific heat of granite is 790 j/kgk while the specific heat of water is 4181 j/kgk.
average temperatures
sep interpret data use the fact that water has a higher specific heat than rock (such as granite) to explain the differences in the temperature curves for the two cities in the graph.

ccc matter and energy wood needs to be given heat energy to reach the temperatures required for combustion to begin. what property of the wood would you need to know to predict how fast the wood would start to burn? explain.

Explanation:

1. San Francisco is near the Pacific Ocean. Water has a higher specific - heat than rock. This means water can absorb or release a large amount of heat energy with a relatively small change in temperature. So, the ocean moderates the temperature of San Francisco, resulting in less temperature variation throughout the year compared to Richmond, VA which is more inland and surrounded by rocks and soil with lower specific - heat values that heat up and cool down more quickly.
2. To predict how fast wood would start to burn, we need to know its specific heat capacity. A lower specific heat capacity means that less heat energy is required to raise its temperature to the ignition point, so it would start to burn faster. Also, factors like the surface area of the wood (more surface area allows for more oxygen contact and faster burning) and the presence of any moisture (moisture requires additional heat to evaporate before combustion can start) are important.

Answer:

1. The ocean near San Francisco, with its high - specific heat water, moderates the city's temperature, causing less variation compared to Richmond, VA which is more affected by lower - specific heat rocks and soil.
2. Specific heat capacity, surface area, and moisture content are important properties to know to predict how fast wood would start to burn.
