A silver bar with a mass of 250. g is heated from 22.0°C to 68.5°C. Assume the specific heat of silver is 0.235 J/g °C. How much heat does the silver bar absorb? Is this endothermic or exothermic?

maybe the spark is gone, love is a weird emotion and there is a possibility he may have found somebody else.

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.

the temperature of the gas, in k, not celsius.
